  - Bugfixing the testcases execusion

    tempest.api.compute.servers.test_server_actions\
    .ServerActionsTestJSON.test_reboot_server_hard
    is working in fuel so do test it.

    The "-" was missing so
    tempest.scenario.test_server_basic_ops
    .TestServerBasicOps.test_server_basic_ops
    was executed on fuel which is known to be
    not working since metadata service is not
    available. That was added already long
    ago but through the not adding
    of the "-" it got added again.
