Bug Description

Recent cleanups in scheduler related to passing full instances caused this to be added to schedule_prep_resize:

125 updated_instance = driver.instance_update_db(context, instance['uuid '],
126 host.host_state.host)

prep_resize should NOT update instance['host'] in the scheduler.. else the check inside of prep_resize() in compute manager comparing instance['host'] against FLAGS.host will always succeed. instance['host'] should be the current (source) host.

    scheduler prep_resize should not update instance['host']

    This is done by the manager once things are ready on the destination
    compute node.

    Fixes bug 1034593

    Also removes now-unneeded update_db argument passed via rpcapi and bumps
    scheduler rpcapi version for prep_resize to 1.4
