Changes HTTP response code for unsupported methods

Requests for resources with an unsupported HTTP method now return a HTTP
response 405 (Method Not Allowed) or 501 (Not Implemented) rather than a
404 (Not Found) for everything.

For example, attempting to DELETE on /v2/images will now return a 405
instead of a 404 and will provide a response header 'Allow' that lists
the valid methods for the resource.

Attempting to use NON_EXISTENT_METHOD on /v2/images will now return a
501.

Attempting to GET on /v2/non_existent_resource will, as expected, return
a 404.

Fixed for v1 and v2.
