Title:
  Wrong error when creating different instances with the same hostname
  into the same DNS domain

Status in OpenStack Compute (nova):
  In Progress

Bug description:
  The bug related to creating different instances with the same hostname
  into the same DNS domain was reported on launchpad
  (https://bugs.launchpad.net/nova/+bug/1283538) and is being solved
  with its review (https://review.openstack.org/#/c/94252/).

  However, the error is thrown when the instance is being built and it
  says "Error: No valid host was found.". It should say something like
  "Error: An instance already exists with the hostname <instance name>".

  Internally, an error with message "The DNS entry %(name)s already
  exists in domain %(domain)s." is being thrown, but it is not shown to
  the caller interface, such as Horizon.
