Cannot auto discover databases and collections (pmm-client container)

Hi!

After enabling --enable-all-collectors option for pmm-client we started to notice errors like:

ERRO[2022-11-23T11:31:15.784+00:00] time=“2022-11-23T11:31:15Z” level=error msg="c

Seems that clusterMonitor user needs some extra roles to list collections and databases.
Tried to add { role: ‘readAnyDatabase’, db: ‘admin’ } to clusterMonitor user, but operator removes that extra role from the user.

Any ideas how to add extra roles to clusterMonitor user ?
