If we use the first one, then the folder to sync using dep-sync will be
conf directory, which have much more other configuration files, which not
yet required to be synced. If it is ok to sync them too,then it's fine.
Second option narrow downs what are to sync, but still have two folder to
sync 'repository/conf/userstores/' and 'repositoty/conf/tenants'. (With the
fact that default user-mgt.xml is also going to be modified and those
modifications needs to be populated in the cluster too, in addition to that
of tenants.)
