  - Drop filtering out services recognized as HTTP

    This patch extends tool used to detect plain HTTP ports to report all
    non-SSL endpoints. Previously it omitted services not recognized as
    HTTP.

    Naming changes were made to reflect purpose of this tool better.

    Issue-ID: INT-1480

  - 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.
