Edwin Kempin 9c6f12c752 RetryHelper: Rename and parameterize the metrics 
The metrics "batch_update/retry_attempt_counts" and
"batch_update/retry_timeout_count" were specific for updates that are
done via BatchUpdate but RetryHelper is also used for other actions
(e.g. account updates). Hence change the metric names so that they are
more generic. Also parameterize the metrics so that values can be
recorded by action type (change update, account update, etc.).

that ultimately timed out

* `proc/jvm/memory/non_heap_committed`: Amount of memory guaranteed for classes,
etc.
* `proc/jvm/memory/non_heap_used`: Amount of memory holding classes, etc.
