---------------------------------------------------------------
[~smeng] The number of active snapshots can't be a counter because the status
might change to deleted or reclaimed and the metric should be able to keep up
with the change.
The best way seems to go over the snapshot table and check the status for every
snapshot and then update the metrics. Counting the number of active snapshots
just for the metrics, seems like an unnecessary load for the system if it has
to happen periodically.
What do you think?
