Add expected failures list for HTTP endpoints tests
This patch is heavily based on previous work by
Morgan Richomme <morgan.richomme@orange.com>
(Change-Id: Ibaed4c5c0e5ae179af0ae317e543c1efdc9ddef2)
It is intended to suppress failure reports on known plain HTTP
endpoints. Introduced list of "expected failures" (or "xfail" for short)
will be shrunk after resolving tickets related to INT-1480 and this
patch will be eventually reverted.
