Invalid 500 response - we should use something better

[lloydwatkin]

When the user is not running services such as the 'channel-directory' service or the media server we really should be returning better error codes than a 500, e.g.

501 Not Implemented
502 Bad gateway
503 Service unavailable

[imaginator]

If search or media servers are down then I guess 502 is the the "right way"

from https://en.wikipedia.org/wiki/List_of_HTTP_status_codes#5xx_Server_Error
502 Bad Gateway
The server was acting as a gateway or proxy and received an invalid response from the upstream server.[2]
