Description

The Ceph Manager has a modular architecture, which allows creating Manager modules written in Python to be loaded at run-time. It would be useful if the Dashboard would be able to:

List all available modules and their status (similar to ceph mgr module ls)
List all services provided by enabled modules (similar to ceph mgr services)
Enable/disable existing modules (similar to ceph mgr module enable <module>)
Modify the configuration of modules

Currently, this functionality is affected by #24648 - enabling or disabling a Mgr module in the Ceph dashboard will cause a restart of the dashboard backend, which would invalidate the current session token. As a result, the user would be logged out of the dashboard, which would be somewhat irritating.

As a workaround, we could display a warning message, informing the user about this behaviour, but this is somewhat ugly.

As it turns out, PR#22833 implements an alternative authentication method based on JSON Web Tokens which will at least ensure that the session does not get lost during the module restart.
