The entitlement entries themselves will be rather simple, consisting
of the objectClasses ipaObject and pkiUser. We will just store
userCertificate in it. The DN will contain the UUID of the entitlement.

Also fix the memberOf attribute for the HBAC services

No longer install the policy or key escrow schemas and remove their
OIDs for now.

This creates a new role, replicaadmin, so a non-DM user can do
limited management of replication agreements.

Note that with cn=config if an unauthorized user performs a search
an error is not returned, no entries are returned. This makes it
difficult to determine if there are simply no replication agreements or
we aren't allowed to see them. Once the ipaldap.py module gets
replaced by ldap2 we can use Get Effective Rights to easily tell the
difference.

We want to only allow a machine to request a certificate for itself, not for
other machines. I've added a new taksgroup which will allow this.

The requesting IP is resolved and compared to the subject of the CSR to
determine if they are the same host. The same is done with the service
principal. Subject alt names are not queried yet.

This does not yet grant machines actual permission to request certificates
yet, that is still limited to the taskgroup request_certs.

We had changed the DN format, I must have missed these ACIs the first
go around.
