[201911][dockers][supervisor] Increase event buffer size for process exit listener (#7106)
Backport of https://github.com/Azure/sonic-buildimage/pull/7083 to the 201911 branch.

#### Why I did it

To prevent error [messages](https://dev.azure.com/mssonic/build/_build/results?buildId=2254&view=logs&j=9a13fbcd-e92d-583c-2f89-d81f90cac1fd&t=739db6ba-1b35-5485-5697-de102068d650&l=802) like the following from being logged:

```
Mar 17 02:33:48.523153 vlab-01 INFO swss#supervisord 2021-03-17 02:33:48,518 ERRO pool supervisor-proc-exit-listener event buffer overflowed, discarding event 46
```

This is basically an addendum to https://github.com/Azure/sonic-buildimage/pull/5247, which increased the event buffer size for dependent-startup. While supervisor-proc-exit-listener doesn't subscribe to as many events as dependent-startup, there is still a chance some containers (like swss, as in the example above) have enough processes running to cause an overflow of the default buffer size of 10.

This is especially important for preventing erroneous log_analyzer failures in the sonic-mgmt repo regression tests, which have started occasionally causing PR check builds to fail. Example [here](https://dev.azure.com/mssonic/build/_build/results?buildId=2254&view=logs&j=9a13fbcd-e92d-583c-2f89-d81f90cac1fd&t=739db6ba-1b35-5485-5697-de102068d650&l=802).

I set all supervisor-proc-exit-listener event buffer sizes to 1024, and also updated all dependent-startup event buffer sizes to 1024, as well, to keep things simple, unified, and allow headroom so that we will not need to adjust these values frequently, if at all.

b70c6f72b2 [dockers][supervisor] Increase event buffer size for dependent-startup (#5247)
When stopping the swss, pmon or bgp containers, log messages like the following can be seen:

```
Aug 23 22:50:43.789760 sonic-dut INFO swss#supervisord 2020-08-23 22:50:10,061 ERRO pool dependent-startup event buffer overflowed, discarding event 34
Aug 23 22:50:43.789760 sonic-dut INFO swss#supervisord 2020-08-23 22:50:10,063 ERRO pool dependent-startup event buffer overflowed, discarding event 35
Aug 23 22:50:43.789760 sonic-dut INFO swss#supervisord 2020-08-23 22:50:10,064 ERRO pool dependent-startup event buffer overflowed, discarding event 36
Aug 23 22:50:43.789760 sonic-dut INFO swss#supervisord 2020-08-23 22:50:10,066 ERRO pool dependent-startup event buffer overflowed, discarding event 37
```

This is due to the number of programs in the container managed by supervisor, all generating events at the same time. The default event queue buffer size in supervisor is 10. This patch increases that value in all containers in order to eliminate these errors. As more programs are added to the containers, we may need to further adjust these values. I increased all buffer sizes to 25 except for containers with more programs or templated supervisor.conf files which allow for a variable number of programs. In these cases I increased the buffer size to 50. One final exception is the swss container, where the buffer fills up to ~50, so I increased this buffer to 100.

7313e7d9bc [teamd]: Add teammgrd in docker-teamd (#2064)
Remove the teamd.j2 templates used for starting the teamd. Add
teammgrd instead to manage all port channel related configuration
changes. Remove front panel port related configurations in
interfaces.j2 templates as well.

Remove teamd.sh script and use teammgrd to start all the teamd
processes. Remove all the logics in the start.sh script as well.

Update the sonic-swss submodule.

Revert "[docker-teamd]: Manage teamd and teamsyncd processes with supervisor (#1137)" (#1156)
This reverts commit a6edef2fa5.

The reason to revert this commit is that it breaks the current nightly test as
no port channel interfaces are get created after boot. teamd failed to start and
complained about 'Cannot allocate memory' possibly due to nlmsg_alloc function
failure.

Will revert this commit to investigate it further before moving to supervisor.
