  - Rewrite TempestResourcesManager

    It now leverages on OpenStack Shade to allow gating OpenStack master
    as asked by TSC. Switching to OpenStack master (OpenStack SDK Rocky)
    requires to change only one line.

    It stops dedicating the network to the user possibly created because
    the support is incomplete (the users have to be registed in
    tempest.conf and the multiprocessing has to be enforced).

    It also writes the second image and the second flavor in tempest.conf.
