Anton Kurbatov 6395b4fe8e Fixing the 500 HTTP code in the metadata service if Nova is down 
If the Nova metadata service is unavailable, the requests.request()
function may raise a ConnectionError. This results in the upper code
returning a 500 HTTP status code to the user along with a traceback.
Let's handle this scenario and instead return a 503 HTTP status code
(service unavailable).

If the Nova service is down and is behind another proxy (such as
Nginx), then instead of a ConnectionError, the request may result in
receiving a 502 or 503 HTTP status code. Let's also consider this
situation and add support for an additional 504 code.

Closes-Bug: #2059032
