…cal process in syncd container exits unexpectedly (sonic-net#3534) Add the same mechanism I developed for the SwSS service in sonic-net#2845 to the syncd service. However, in order to cause the SwSS service to also exit and restart in this situation, I developed a docker-wait-any program which the SwSS service uses to wait for either the swss or syncd containers to exit.

Run etiher
sudo pkill -11 <critical_process_in_syncd_container>, and observe that syncd service exits, swss and all dependent services exit, then all of those services start back up.
