In upgrade scenarios, where config_db.json is not carry forwarded to new image, it could be left w/o TACACS credentials.
Added a service to trigger 5 minutes after boot and restore TACACS, if /etc/sonic/old_config/tacacs.json is present.
How I did it
By adding a service, that would fire 5 mins after boot.
This service apply tacacs if available.
How to verify it
Upgrade and watch status of tacacs.timer & tacacs.service
You may create /etc/sonic/old_config/tacacs.json, with updated credentials
(before 5mins after boot) and see that appears in config & persisted too.
This PR aims to monitor the memory usage of streaming telemetry container and restart streaming telemetry container if memory usage is larger than the pre-defined threshold.

Why I did it
The service file generate_monit_config.service is used to generate the Monit configuration file from template. I also should install this service file and enable it.
How I did it
I appended this service file name at the end of /etc/sonic/generated_services.conf.
How to verify it
I verified this on the device str2-7260cx3-acs-1.

Why I did it
This PR aims to monitor critical processes in router advertiser and dhcp_relay containers by Monit.
How I did it
Router advertiser container only ran on T0 device and the T0 device should have at least one VLAN interface
which was configured an IPv6 address. At the same time, router advertiser container will not run on devices of which
the deployment type is 8.
As such, I created a service which will dynamically generate Monit configuration file of router advertiser from a
template.
Similarly Monit configuration file of dhcp_relay was also generated from a template since the number of dhcrelay process in dhcp_relay container is depended on number of VLANs.
How to verify it
I verified this implementation on a DuT.
The Portchannels were not getting cleaned up as the cleanup activity was taking more than 10 secs which is default docker timeout after which a SIGKILL will be send.

[multi_asic][vs]: Add dependency in teamd service to start after topology service.
- Why I did it
In multi-asic VS, topology service is run after database service to set up the internal asic topology.
swss and syncd have a dependency to start after topology service is run so that the interfaces are moved to right namespace and created in the right namespace. In case of multi-asic vs, during the initial boot up, when there is no configuration added, teamd service starts and swss/syncd do not start as topology service does not start. Upon loading configuration using config_db or minigraph, swss and sycnd start up , but teamd is not restarted as swss is not stopped and started. This causes teamd to be in a bad state and requires a reload of config.
- How I did it
Add dependency in teamd service to start after topology service is completed.
- How to verify it
No change in single asic vs or platform.
No change in multi-asic regular image.
Change only in multi-asic VS. Bring up a multi-asic VS image without any configration, teamd service will fail to start due to dependency failure. Load minigraph, start topology service, load configuration, ensure all services come up.

Following changes were done for ebtables:
- Support for Multi-asic platforms. Ebtable filters are installed in namespace for multi-asic and not host. On Single asic installed on host.
- For Multi-asic platforms we don't want to install on host otherwise Namespace-to-Namespace communication does not happens since ARP Request are not forwarded.
- Updated to use text file to restore ebtables rules then the binary format. Rules are restore as part of Database docker init instead of rc.local
- Removed the ebtable service files for buster as not needed as filters are restored/installed as part of database docker init.

Fixes#5663
- Why I did it
It's currently possible for the SNMP timer to conflict with config reload (specifically if the timer triggers while config reload is stopping the SWSS service). config reload triggers SWSS to shutdown, which causes SNMP to shutdown, which conflicts with the SNMP timer causing SNMP to startup. See the linked issue for more details.
- How I did it
Including the After ordering dependency forces the SNMP timer to wait until SWSS finishes stopping, preventing the conflict. If there is an ordering dependency between two units (e.g. one unit is ordered After another), if one unit is shutting down while the other is starting up, the shutdown will always be ordered before the startup. In this case, that means that the SNMP timer is forced to wait for the SWSS shutdown to complete. Only then can the SNMP timer proceed. See here for more details.
It's important to note that the After dependency will not cause SWSS to be started when the SNMP timer fires (assuming that SWSS has not yet been started). The existing Requisite dependency in the SNMP service will also not cause SWSS to be started, instead it will cause the SNMP service to fail if SWSS is not active.

Added new flag value 'always_enabled' for the state and auto-restart field of feature table
init_cfg.json is updated to initialize state field of database/swss/syncd/teamd feature and auto-restart field of database feature
as always_enabled
Once the state/auto-restart value is initialized as "always_enabled" it is immutable and cannot be change via feature config commands. (config feature..) PR#Azure/sonic-utilities#1271
