    Removes potentially bad exit value from accepted list in Quobyte volume driver
    
    This disallows exit code 4 in the list of valid exit codes of the execute
    call for mounting Quobyte volumes. As exit code 0 is the default value
    for the allowed exit codes the whole check_exit_codes argument is
    omitted.
    Furthermore this updates the (dis-)connect volume sync locks to be
    Quobyte specific.

Title:
  Quobyte driver may fail to raise an error upon error code 4 on volume
  mounting

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  The Quobyte libvirt volume driver currently accepts exit codes [0,4] when mounting a Quobyte volume (https://github.com/openstack/nova/blob/master/nova/virt/libvirt/volume/quobyte.py#L55).
  However error code 4 might be thrown in acceptable (already mounted) and unacceptable cases (specific bad state). As the driver already checks for existence of the mount when connecting a volume the error code should be removed as acceptable and failed upon.
