Merge pull request #2152 from Bobfrat/fix_event_subscriber

M101 - Fix event driven mission logic
remove tests and direct supporting code in platform driver related with concept of connecting/disconnecting instruments to platform ports and sync/checksum operations.

All of this per recent CI-OMS interface simplification. Note, these elements are still present in underlying supporting classes, but not exercised anymore from the platform agent/driver.
Release Version 3.0.2
