[CBM] Make it easier to config an archive for capella provisioned

What is the problem?
Currently to take a backup of a provisioned capella cluster you need to specify a lot of disable flags:

--disable-analytics --disable-cluster-analytics --disable-bucket-query --disable-cluster-query

(from the docs). This can easily trip people up.

Note 1:

For 7.6, also need --disable-users and for restore, also need --disable-views , so for simplicity, specify same for both backup and restore

--disable-analytics --disable-cluster-analytics --disable-bucket-query --disable-cluster-query --disable-views --disable-users

Note 2:

Restoring a self-managed cluster backup to the Capella cluster using cbbackupmgr is also an important use case.  Making this data migration use case easier for customers is a priority per the Cloud Architects team.  So, need to make sure that there's an easier way for customers to specify that they are restoring to a Capella provisioned cluster than having to specify all the disable options in Note 1.

What is the solution?
We should add a new flag for config that specifies it is a Capella provisioned backup (--capella). This flag should be stored in the repository backup config and during a backup it should be used to disable services we know do not work with Capella.

We should also add the same flag to restore so that if a user is restoring from a backup of an on-prem cluster they can restore it to Capella easily.
