    Log a warning when getting lvs and vgs takes longer than 60 seconds

    We know something is causing lvs/vgs commands to block while deleting a
    volume and this is causing Tempest to timeout while waiting for the
    volume to be deleted. What we don't have right now is very good
    (specific) logging when this happens, unless we get messages in syslog
    for lvm tasks taking more than 120 seconds, but that doesn't always
    happen when we see the volume delete timeout in Tempest.

    This patch adds a check for when getting logical volumes and volume
    groups takes longer than 60 seconds and logs a warning if that happens.
    This is helpful in production also because the default interval for
    periodic tasks is 60 seconds so having these take longer than that time
    could cause periodic tasks to block up on each other and you'll get
    warnings from the FixedIntervalLoopingCall in oslo which is controlling
    the task runs.
