dashboards: show max number of active merges instead of cumulative

Browse Source 
The cumulative number of active merges could be red herring
as it its value depends on the number of vmstorages.
For example, vmstorage could be added or removed and this will affect
the panel.
Or, each vmstorage could start a merging process (i.e. for downsampling)
and visiually it could look like a massive change.
