ipareplica: Replace ipaserver_master_password, remove ipaserver_setup_ntp

ipaserver_master_password and ipaserver_setup_ntp have been linked from
the ipaserver role before. With the move of the module_utils parts to the
specific role locations the use of ipaserver modules leads to the missing
dependency ansible_ipa_server, that is now only available in the server
role.

The ipaserver_master_password module has been replaced by the ipareplica
specific ipareplica_master_password module. The ipaserver_setup_ntp module
has been removed as the time related changes for replica are done in the
client install part.

Fixes: #59 (Module is missing interpreter line)
