Release justification: decrease splunk costs
Previously if remote node containing replica was removed,
sidetransport connection will keep trying to connect to non-existing
node until server is stopped regardless of connection status.
This is not good as it will keep trying every second wasting
resources and also spamming log with message every 10 seconds.
This patch moves liveness check to the top of runloop to terminate
it early as soon as connection is closed.
Release note: None
Fixes #80156
