Adding or deleting user events are not registered

[vento-di-pace]

Harbor doesn't register events of user management, such as adding or deleting users. I think it's need to be added, it relates to control access to repositories.

I really want to work on this issue @Vad1mo

[Vad1mo]

the goal would be here to extend the audit-log capabilities and track also the user lifecycle events like user login, user create, user delete..

Here is an example PR that extends the Audit logs #19725

However, before jumping into the issue, there is currently the idea to rewrite the audit log capability. @wy65701436 can provide some more context into here.
