    Enable os_tempest for master multinode jobs

    As overcloud clouds.yaml support landed in Tripleo for train
    release and os_tempest ansible role is used for running
    tempest. Multinode container job runs for other releases also
    so it updates the fs010 to run os_tempest for master only.

    Closes-Bug: #1837019
