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

[Samuel de Medeiros Queiroz]

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.

https://github.com/openstack/nova/blob/master/nova/network/floating_ips.py#L628-L630 is where this is leaking up, it would be tracing up from there to figure out why this isn't getting exposed on the surface.

The age and number of assignee changes suggest that this isn't really
a low-hanging-fruit. I'm removing the tag to not confuse new folks who
are searching for that tag.
