Why I did it

To fix teamd signal handling:

Sep 27 15:36:40.755013 sonic INFO teamd#supervisord 2021-09-27 15:36:40,754 INFO exited: tlm_teamd (terminated by SIGUSR1; not expected)
Sep 27 15:36:41.766193 sonic INFO teamd#/supervisor-proc-exit-listener: Process 'tlm_teamd' exited unexpectedly. Terminating supervisor 'teamd'
