[TRAFODION-2881] HA fixes
Fixed multiple problems in monitor Allgather() socket reconnect logic.
- Separated node down detection logic from communication errors and timeouts
to better handle multiple failure scenarios
- Better handling network resets
- Additional trace information
- Fixed 'node up' hang in monitor shell due to TmSync race condition

> URL: https://issues.apache.org/jira/browse/TRAFODION-2881
> Project: Apache Trafodion
> Issue Type: Bug
> Components: foundation
> Affects Versions: 2.3
> Reporter: Gonzalo E Correa
> Assignee: Gonzalo E Correa
> Fix For: 2.3
>
>
> Inflicting server failure in certain modes will cause multiple monitor process to also bring their nodes down along with the intended target of the test.
> Server down modes:
> init 6
> reboot -f
> shutdown -r now
> shell node down command
> In addition, after a server down, the shell 'node up' command will also fail intermittently. This requires a longevity HA test to down and up nodes over a long period of time like 24-48 hours.
