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.

This makes it possible to install the debug symbols if needed. Also install
the package into the debug version of sonic-dhcp-relay container.

* 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.
* [service] Restart SwSS Docker container if orchagent exits unexpectedly
* Configure systemd to stop restarting swss if it attempts to restart more than 3 times in 20 minutes

* Also update journald.conf options
* Remove 'PartOf' option from unit files
* Add '$(SUPERVISOR_PROC_EXIT_LISTENER_SCRIPT)' to new shared docker-orchagent makefile

* Reorder patches to apply bug fix first, then features
* Extend makefile to build debug Docker image
* Update commit that series file applies against
* Add docker-dhcp-relay/Dockerfile to .gitignore
* Add isc-dhcp-relay .deb package to image build process, along with my Option 82 patch

* [docker-config-engine]: introduce docker sonic config engine
sonic config engine provide the sonic configure engine for all sonic
dockers that rely on the engine to generate runtime configuration.
