    Add fbp_copy_plugin to avoid attr error

    We do not have docker containers on master node anymore,
    but at the same time want to assert plugin
    installation from directory that differs from build one.
    So add copy method into FuelPluginBuilder()

    Aslo add self.show_step() invocation

    Closes-Bug: #1548348

    Update release version into reboot plugin

    For now test will fail on attempts to enable it in cluster attributes,
    according to release version in plugin metadata
    in not compatible with mitaka-9.0.
    In this patch we just update this data.
