[202012][dockers][supervisor] Increase event buffer size for process exit listener; Set all event buffer sizes to 1024 (#7203)
#### Why I did it Backport of https://github.com/Azure/sonic-buildimage/pull/7083 to the 202012 branch. 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. |

[supervisor] Install vanilla package once again, install Python 3 version in Buster container (#5546)
**- Why I did it** We were building a custom version of Supervisor because I had added patches to prevent hangs and crashes if the system clock ever rolled backward. Those changes were merged into the upstream Supervisor repo as of version 3.4.0 (http://supervisord.org/changes.html#id9), therefore, we should be able to simply install the vanilla package via pip. This will also allow us to easily move to Python 3, as Python 3 support was added in version 4.0.0. **- How I did it** - Remove Makefiles and patches for building supervisor package from source - Install Python 3 supervisor package version 4.2.1 in Buster base container - Also install Python 3 version of supervisord-dependent-startup in Buster base container - Debian package installed binary in `/usr/bin/`, but pip package installs in `/usr/local/bin/`, so rather than update all absolute paths, I changed all references to simply call `supervisord` and let the system PATH find the executable to prevent future need for changes just in case we ever need to switch back to build a Debian package, then we won't need to modify these again. - Install Python 2 supervisor package >= 3.4.0 in Stretch and Jessie base containers |

[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.

This needs root permissions, and one of the tests that is performed is whether the user can create a character special file in the filesystem (using mknod). On most NFS deployments, `root` is the least privileged user, and cannot run mknod. Also, attempting to run commands like rm or mv as root would fail due to permission errors, since the root user gets mapped to an unprivileged user like `nobody`. This commit changes the location of the Debian filesystem to `/fsroot`, which is a tmpfs mount within the slave Docker. The default squashfs, docker tarball and zip files are also created within /tmp, before being copied back to /sonic as the regular user. The side effect of this change is that the contents of `/fsroot` are no longer available once the slave container exits, however they are available within the squashfs image.
