Joe LeVeque 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.

HOWTO Use Virtual Switch (VM)

  1. Install libvirt, kvm, qemu
sudo apt-get install libvirt-clients qemu-kvm libvirt-bin
  1. Create SONiC VM for single ASIC HWSKU
$ sudo virsh
Welcome to virsh, the virtualization interactive terminal.

Type:  'help' for help with commands
       'quit' to quit

virsh # 
virsh # create sonic.xml
Domain sonic created from sonic.xml

virsh # 
  1. Create SONiC VM for multi-ASIC HWSKU Update sonic_multiasic.xml with the external interfaces required for HWSKU.
$ sudo virsh
Welcome to virsh, the virtualization interactive terminal.

Type:  'help' for help with commands
       'quit' to quit

virsh #
virsh # create sonic_multiasic.xml 
Domain sonic created from sonic.xml

virsh #

Once booted up, create a file "asic.conf" with the content:
NUM_ASIC=<Number of asics>
under /usr/share/sonic/device/x86_64-kvm_x86_64-r0/
Also, create a "topology.sh" file which will simulate the internal
asic connectivity of the hardware under
/usr/share/sonic/device/x86_64-kvm_x86_64-r0/<HWSKU>
The HWSKU directory will have the required files like port_config.ini
for each ASIC.

Having done this, a new service "topology.service" will be started
during bootup which will invoke topology.sh script.

3. Access virtual switch:

    1. Connect SONiC VM via console
    ```
    $ telnet 127.0.0.1 7000
    ```
    
    OR

    2. Connect SONiC VM via SSH
        
        1. Connect via console (see 3.1 above)

        2. Request a new DHCP address
        ```
        sudo dhclient -v
        ```
        
        3. Connect via SSH
        ```
        $ ssh -p 3040 admin@127.0.0.1
        ```
