Christian Heimes 025facb85c Add hidden replica feature
A hidden replica is a replica that does not advertise its services via
DNS SRV records, ipa-ca DNS entry, or LDAP. Clients do not auto-select a
hidden replica, but are still free to explicitly connect to it.

Fixes: https://pagure.io/freeipa/issue/7892
