fix permission: Read Replication Agreements
    
    This permission cannot be MANAGED permission because it is located in
    nonreplicating part of the LDAP tree.
    
    As side effect, the particular ACI has not been created on all replicas.
    
    This commit makes Read Replication Agreements non managed permission and
    also fix missing ACI on replicas.
