Reliability improvements for worker-host communication

[liliankasem]

We have seen many CRIs where out-of-proc language workers fail to start or call back to the host within the defined timeout period. We need to identify the root-cause and fix all the potential reasons, however currently this is very difficult as we are dealing with a long tail of various issues from different components and levels. To do this, we need to improve the reliability of host-worker communication and fix potential bugs.

This epic will keep track of issues that could help us improve worker-host reliability:
