Resetting the volume performance counters does not affect the partial read counters #356

Code inspection shows that only the performance_counters are reset - all other counters (MD / SCO cache hits + misses, partial read counters etc.) are not reset.

@redlicha how much work would this be to fix? is there anything that fails if we don't reset everything. Can monitoring work around this by doing a diff between the counters?

It's "only" a question of consistency / avoiding special casing in consumers of the data. Ballpark estimate +/- 1d?
