Fix replication races in Dogtag admin code
DogtagInstance.setup_admin and related methods have multiple LDAP
replication race conditions. The bugs can cause parallel
ipa-replica-install to fail.
The code from __add_admin_to_group() has been changed to use MOD_ADD
ather than search + MOD_REPLACE. The MOD_REPLACE approach can lead to
data loss, when more than one writer changes a group.
setup_admin() now waits until both admin user and group membership have
been replicated to the master peer. The method also adds a new ACI to
allow querying group member in the replication check.
