    Start up glance-powervc driver in Juno Release

    In Juno Release , there are four files in the Glance Component deleted
     in the directory "glance/openstack/common" , based on
    https://github.com/openstack/glance/commit/c3ff558fc0b8eab6117901a746f97a2800d7d02f,
     but glance-powervc driver need the ServiceLauncher to launch the driver service ,so
     it starts failed.

    The solution is to change to user nova ServiceLauncher to launch the
     service by modifing import path in the file bin/glance-powervc and
     manager/manager.py
