Jan Cholasta e137f305ed aci: allow members of ipaservers to set up replication 
Add ACIs which allow the members of the ipaservers host group to set up
replication. This allows IPA hosts to perform replica promotion on
themselves.

A number of checks which need read access to certain LDAP entries is done
during replica promotion. Add ACIs to allow these checks to be done using
any valid IPA host credentials.
