[LU-13055] add ability for named Changelog consumers

• Type: Improvement
• Status: Closed
• Priority: Minor
• Resolution: Fixed
• Fix Version/s: Lustre 2.15.0, Lustre 2.12.8
• Assignee: Mikhail Pershin
• Reporter: Andreas Dilger

Description

Currently Lustre Changelog consumers are always named e.g. "cl1" or "cl14". It would be useful to be able to declare the changelog username (e.g. "cl-rbh" or "cl-audit") so that it is clear who the Changelog users are, and to avoid duplicate changelog registrations. Otherwise, it can happen that the original Changelog user registration can be lost, and the application registers a new user, and the old user causes the Changelog records to accumulate.
