Subject: Support external/pre-provisioned authoritative cluster DNS (#690)

* Document how to use fully external DNS servers w/o provisioning
  dns servers group with Heat.

* Document how to use a mixed servers setup for dynamic records
  updates mathing public or private views.

* Allow custom nsupdate key names for OSP10 dns service compatibility.
  The osp-dns configures the named service with the fixed key_name
  'update-key'. Add optional key_name for the external_nsupdate_keys
  public section to allow custom key names.
