HDDS-9334 added the ability to specify a prefix for threads created in common/framework code (EventQueue, BackgroundService, etc.). These are used by multiple components (SCM, OM, DN). However, HDDS-9334 has set the actual prefix only for some of the usages as a proof of concept.
Goals of this task:
- replace all occurrences of empty thread name prefix in OM with the real one
- apply the same prefix to all other threads created in OM code.
