For #28196
This PR depends on PR https://github.com/fleetdm/fleet/pull/28832
This PR adds support for excludeAttributes=members, which is being used
by Microsoft Entra ID.
This PR modifies the primary key of host_scim_user table to be host_id.
This should have been done initially and has added accidental complexity
and maintainability challenges, so we are doing it now. This means a
host can have a maximum of 1 SCIM user associated with it. A SCIM user,
on the other hand, can be associated with multiple hosts.
