    Sync processutils and lockutils from oslo with deps
    
    This is a sync of processutils and lockutils from oslo-incubator
    along with their dependencies.
    
    The main target for the sync is to pick up the get_worker_count() method
    in commit 85f178489a128a04a7ee3ed44018403caa109ef0 so that we can set
    glance-api workers equal to the number of CPUs on the host.
    
    lockutils is also copied over due to the nature running multiple
    workers and how the glance functional tests are setup, it'd be
    prudent to have the latest lockutils code since it hasn't been updated
    in over six months.
    
    The change to require posix_ipc is due to commit
    edce46cf5efd6d738d379205f9bf526a498845e3 in lockutils.
