Why I did it
sonic_dhcp_server.whl contains not only dhcp_server functionality but also part of dhcp_relay functionality, the existing naming is not appropriate.
Modify j2 template files in docker-dhcp-relay. Add dhcprelayd to group dhcp-relay instead of isc-dhcp-relay-VlanXXX, which would make dhcprelayd to become critical process.
In dhcprelayd, subscribe FEATURE table to check whether dhcp_server feature is enabled.
2.1 If dhcp_server feature is disabled, means we need original dhcp_relay functionality, dhcprelayd would do nothing. Because dhcrelay/dhcpmon configuration is generated in supervisord configuration, they will automatically run.
2.2 If dhcp_server feature is enabled, dhcprelayd will stop dhcpmon/dhcrelay processes started by supervisord and subscribe dhcp_server related tables in config_db to start dhcpmon/dhcrelay processes.
2.3 While dhcprelayd running, it will regularly check feature status (by default per 5s) and would encounter below 4 state change about dhcp_server feature:
A) disabled -> enabled
In this scenario, dhcprelayd will subscribe dhcp_server related tables and stop dhcpmon/dhcrelay processes started by supervisord and start new pair of dhcpmon/dhcrelay processes. After this, dhcpmon/dhcrelay processes are totally managed by dhcprelayd.
B) enabled -> enabled
In this scenaro, dhcprelayd will monitor db changes in dhcp_server related tables to determine whether to restart dhcpmon/dhrelay processes.
C) enabled -> disabled
In this scenario, dhcprelayd would unsubscribe dhcp_server related tables and kill dhcpmon/dhcrelay processes started by itself. And then dhcprelayd will start dhcpmon/dhcrelay processes via supervisorctl.
D) disabled -> disabled
dhcprelayd will check whether dhcrelay processes running status consistent with supervisord configuration file. If they are not consistent, dhcprelayd will kill itself, then dhcp_relay container will stop because dhcprelayd is critical process.

##### Work item tracking
- Microsoft ADO **(number only)**: 14807420
#### How I did it
Reduce linux capabilities in privileged flag
#### How to verify it
Run dhcprelay sonic-mgmt tests
Check container's settings: Privileged is false and container only has default Linux caps, does not have extended caps.
```
admin@vlab-05:~$ docker inspect dhcp_relay | grep Privilege
"Privileged": false,
admin@vlab-05:~$ docker exec -it dhcp_relay bash

Why I did it
To reduce the container's dependency from host system

How I did it
Move the k8s container startup script to config engine container, other than mount it from host.
How to verify it
Check file path(/usr/share/sonic/scripts/container_startup.py) inside config engine container.

#### Why I did it
To fix the timezone sync issue between the containers and the host. If a certain timezone has been configured on the host (SONIC) then the expectation is to reflect the same across all the containers.
This will fix [Issue:13046](https://github.com/sonic-net/sonic-buildimage/issues/13046).
For instance, a PST timezone has been set on the host and if the user checks the link flap logs (inside the FRR), it shows the UTC timestamp. Ideally, it should be PST.
Why I did it
src/dhcprelay is being split out to be its own submodule.
How I did it
Add existing dhcprelay commits into the new repo.
Clean up Makefile (sonic-net/sonic-dhcp-relay@772625f)
Add LGTM config (sonic-net/sonic-dhcp-relay@5cc0889)
Add Azure pipeline config (sonic-net/sonic-dhcp-relay@c79cdb7)
Add submodule reference, renaming most references of dhcp6relay to dhcprelay (to reflect that this will not just be for IPv6 in the future).
How to verify it
Successful run of LGTM is tested at sonic-net/sonic-dhcp-relay#4. Failure run of LGTM is tested at sonic-net/sonic-dhcp-relay#3.
Azure pipeline is run for each commit/PR, and will build for amd64, armhf, and arm64. UT/code coverage check is not yet done.

Enable dbgsym package for dhcpmon.
Allow CFLAGS and LDFLAGS from environment variables to be used
in the dhcp6relay build. This makes sure that the -O2 flag from
dpkg-buildflags gets used.
Finally, enable all hardening flags in dpkg-buildflags for
dhcp6relay and dhcpmon. The change from the default set of flags is that
during linking, immediate binding of symbols is done instead of lazy
binding.

As part of this, update the isc-dhcp package to match the Bullseye
version (this fixes some compile errors related to BIND), clean up some
of the build dependencies and runtime dependencies for debian packaging,
and use the default Boost version to compile against instead of
explicitly saying using 1.74.

- Why I did it
Make DHCP relay docker an extension. DHCP relay now carries dhcp relay commands CLI plugin and has a complete manifest.
It is installed as extension if INCLUDE_DHCP_REALY is set to y.
DEPENDS on #5939
- How I did it
Modify DHCP relay docker makefile and dockerfile. Make changes to sonic_debian_extension.j2 to install sonic packages.
I moved DHCP related CLI tests from sonic-utilities to DHCP relay docker.
This PR introduces a way to write a plugin as part of docker image and run the tests from cli-plugin-tests directory under docker directory.

This PR is part of SONiC Application Extension
Depends on #5938
- Why I did it
To provide an infrastructure change in order to support SONiC Application Extension feature.
- How I did it
Label every installable SONiC Docker with a minimal required manifest and auto-generate packages.json file based on
installed SONiC images.
- How to verify it
Build an image, execute the following command:
admin@sonic:~$ docker inspect docker-snmp:1.0.0 | jq '.[0].Config.Labels["com.azure.sonic.manifest"]' -r | jq
Cat /var/lib/sonic-package-manager/packages.json file to verify all dockers are listed there.
* First cut image update for kubernetes support.
With this,
1) dockers dhcp_relay, lldp, pmon, radv, snmp, telemetry are enabled
for kube management
init_cfg.json configure set_owner as kube for these
2) Each docker's start.sh updated to call container_startup.py to register going up
As part of this call, it registers the current owner as local/kube and its version
The images are built with its version ingrained into image during build
3) Update all docker's bash script to call 'container start/stop/wait' instead of 'docker start/stop/wait'.
For all locally managed containers, it calls docker commands, hence no change for locally managed.
4) Introduced a new ctrmgrd service, that helps with transition between owners as kube & local and carry over any labels update from STATE-DB to API server
5) hostcfgd updated to handle owner change
6) Reboot scripts are updatd to tag kube running images as local, so upon reboot they run the same image.
7) Added kube_commands.py to handle all updates with Kubernetes API serrver -- dedicated for k8s interaction only.
- move single instance services into their own folder
- generate Systemd templates for any multi-instance service files in slave.mk
- detect single or multi-instance platform in systemd-sonic-generator based on asic.conf platform specific file.
- update container hostname after creation instead of during creation (docker_image_ctl)
- run Docker containers in a network namespace if specified
- add a service to create a simulated multi-ASIC topology on the virtual switch platform

DHCP relay MONitor (dhcpmon) keeps track of DORA messages. If DHCP Relay
is detected to be not forwarding DORA message, dhcpmon will log such event
to syslog. Under the hood dhcpmon keeps counts of clients DR messages,
forwarded DR messages, DHCP server OA messages, and forwarded OA messages.
dhcpmon will check every 12 sec (configurable) if counts are monotonically
increasing and record snapshot of those counters. dhcpmon will report
discrepancies when detected between current counters and snapshot counters.

* Added debug symbols to many debug dockers.
* For debug images *only*:
1) Archive source files into debug image
2) Archived source is copied into /src
3) Created an empty dir /debug
4) Mount both /src as ro & /debug as rw into every docker
5) Login banner will give some details on /src & /debug
6) Devs can copy core file into /debug and view it from inside a container.
7) Dev may create all gdb logs and other data directly into /debug.
* Dropped redundant REDIS_TOOLS per review comments.
* Added debug symbols to frr package and hence FRR based BGP docker.
* 1) Moved dbg_files.sh to scripts/
2) Src directories to archive are now collected from individual Makefiles.
3) Added few more debug symbols
4) Added few more debug dockers.
Here after no more changes except per review comments.
To debug:
Install required version of debug image in Switch or VM.
Copy core file into /debug of host
Get into Docker
gdb /usr/bin/<daemon> -c /debug/<your core file>
set directory /src/... <-- inside gdb to get the source
For non-in-depth debugging:
Download corresponding debug Docker image (docker-...-dbg.gz) to your VM
Load the image
Run image with entrypoint as 'bash' with dir containing core mapped in.
Run gdb on the core.
