David Turner 7e82a4f78c Do not log no-op reconnections at DEBUG (#53469)
Today the NodeConnectionsService emits a DEBUG-level log message each time it
calls TransportService#connectToNode, which happens for every node in the
cluster every ten seconds, and also at every cluster state update. That's a lot
of log messages. Most of these calls are no-ops and can be ignored, but if the
call was not a no-op then it may be worth investigating further. Since the logs
do not distinguish the interesting and uninteresting cases, they are not
useful.

This commit distinguishes the two cases and pushes the noisy logging for the
common no-op case down to TRACE level, leaving only useful and actionable
information in the DEBUG-level logs.
