quotas: do not fail to set/delete if an endpoint is missing

If you attempted to set or delete a nova quota but the neutron endpoint
was missing but the network service existed, it would fail. The show
command handled this gracefully and had options to allow you to just
show the services that you were interested in. This lead to poor UX.

+    When attempting to set or delete a quota for nova the command can fail if
+    the endpoint for the service does not exist but the service does. An
+    endpoint is a service at a specific region for a specific interface. The
+    other quota commands gracefully handle this leading it not being possible
+    to set or delete a quota in this case but to be able to see it.
