[Bug 1402339] [NEW] Status code from HEAD requests must be consistent

 

Public bug reported:

Bug 'HEAD and GET inconsistencies in Keystone' [1] reported that HEAD
should be identical to GET except that there is no body returned, as
defined on the HTTP 1.1 specification [2], then 200 status code have to
be returned [3].

Some inconsistencies were removed, but there is still some work to be
done:

1) For all HEAD APIs:
   a) Fix return from 204 to 200, if change applies;
   b) Fix related tests, e.g checking a grant [4];
   c) Fix identity v3 API specification, that reports 204 is returned on most of HEAD APIs (except for /auth/tokens).
2) Default status code asserted on test_v3 [5] should be 200 instead of 204
