  - Merge "RBD: Wrap RBD calls in native threads"
  - RBD: Wrap RBD calls in native threads
    
    librbd methods call lower level C code which runs in native code
    and isn't aware about the eventlet threads hence hangs the eventlet
    loop until the native code is finished.
    This could cause problems when we are creating multiple images
    with large size where one call to librados can cause the process to
    hang and other operations can starve for execution and error out.
    This patch wraps each RBD call in it's own native thread that won't
    affect other RBD call from executing.
    
    Note that since glance can run under eventlet *or* native threads
    with something like uwsgi, this only delegates to an eventlet worker
    when we are running in that environment.
    
    Note: This was originally merged as commit
    27ab8a6aeb7a59bc56ed0ad26ffb5a83d426b447, but without the handling
    for non-eventlet cases.
