As an JIRA Administrator for JIRA Datacenter I want to log CachedReferences flush events

Problem Definition

Follow-up from JRASERVER-62707 regarding CachedReferences

Suggested Solution

Add INFO logging event for cache reset event and additional DEBUG logging with stackrace to track source the flush event.

Implemented solution

• In fixed JIRA version, there is a logging for cache reset events for CachedReferences (same as for JRASERVER-62707):
• Please note that this logging has no performance impact.
• How to enable logging for cache flush events:
  1. Navigate to Cog Icon > System > Logging and profiling
  2. Find com.atlassian.cache.event and set it to INFO level
