There have been missing settings that have not been provided to
ipareplica_setup_adtrust. These are: enable_compat, rid_base and
secondary_rid_base.

The settings rid_base and secondary_rid_base are now initialized in
ipareplica_prepare and propagated in the results.

The two settings netbios_name and reset_netbios_name are placed in the
adtrust binding in the adtrust.install_check call. These are now saved
when ipareplica_prepare finishes and are written back in the fist steps of
ipareplica_setup_adtrust to make adtrust.install working.

The settings add_sids and add_agents are now initialized in
ansible_ipa_replica in the same way as in ServerMasterInstall. These
settings are fixed in the replica deployment.
