Update git submodules

* Update docs/submodules/barometer from branch 'master'
  - Merge "[functest] Update tests for Aodh"
  - [functest] Update tests for Aodh
    
    * Update the check for timestamp to use state_timestamp instead
      state_timestamp indicates the last change in state of the alarm,
      timestamp is the last update to the alarm settings. This is not
      what we're looking for with aodh tests, so check the state update
      instead.
    * Trigger an alarm state change before checking whether the alram
      was updated. Notification in collectd aren't necessarily updated
      at a regular interval, so we have to do some action and check whether
      the alarm is updated.
