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

```
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.

The SNMP subagent implements ipCidrRouteTable. If there is no nexthops
for default route, ie. switch isolated, the SNMP subagent will response
'no instance'. Then snmpd will response kernel routes, which include
non-front panel interfaces. To remove snmpd native implementation, we
only expose SNMP subagent's implementation.
- Consolidate config.sh and start.sh scripts into one script (start.sh)
- Solve issue #435 - All dockers now run supervisord as their ENTRYPOINT
- All stdout/stderr output from processes managed by supervisord is now sent to syslog instead of their own files
- Supervisord log messages are now also sent to syslog
- Removed unused smartmontools package from docker-platform-monitor
* Adding support for V2 in SNMP/LLDP (-sv2 postfix)
* Fixes for V1 containers: logging
* Fixes for V1 LLDP: limit LLDP to Front-panel or MGMT interfaces.
