Ceph » Orchestrator

when creating RGW running

# ceph orch apply rgw --realm_name=default --zone_name=default 1 monitor2:192.168.122.151
["Deployed rgw.default.default.pnxfft on host 'monitor2'"]

RGW service is created and running on target host. Also ceph config is
updated:

mgr                               advanced mgr/orchestrator/orchestrator  cephadm                                                             
  client.rgw.default              advanced rgw_realm                      default
  client.rgw.default.default      advanced rgw_zone                       default 
*

after updating RGW (going to change zone) ceph config contains
configurations for both - RGW with old zone name and new zone name.
On target host there is new service for rgw with new zone name along with
running RGW service with old zone name

 mgr                               advanced mgr/orchestrator_cli/orchestrator  cephadm                                                             
   client.rgw.default              advanced rgw_realm                          default
   client.rgw.default.default      advanced rgw_zone                           default
   client.rgw.realm1               advanced rgw_realm                          realm1
   client.rgw.realm1.default       advanced rgw_zone                           default

I suppose that update should perform changing of the name and not adding new
seervice. If user would like to add new service he would use 'add' parameter
instead of 'update'.
