INFO log message is missing when a repository is deleted/created/changed

• creating a repository
• deleting a repository
• changing settings of a repository

Are system changes and all system level changes need to be logged visibly at default log levels.

For group repositories, the group members added or removed need to be logged explicitly. A concern is that logging the entire active group member list ( even the first level ) would create a very verbose log statement in some circumstances - this is why only first level additions and removals are requested. Yes - when the repo is first created, listing all the first level member ids is expected.
