   Problem Summary: Meta Service stores ALTER COMPUTE GROUP properties as a 
complete replacement, but the FE periodic checker merged only changed keys into 
its in-memory metadata. Properties removed from Meta Service therefore remained 
in FE indefinitely. Compare the complete snapshots and publish a validated 
replacement map so additions, updates, and removals converge consistently.
   
   Compute group property removals now propagate from Meta Service to FE during 
periodic synchronization.

       - fe-core Checkstyle
   - Behavior changed: Yes (FE removes compute group properties absent from the 
authoritative Meta Service snapshot)
   - Does this need documentation: No
