Description

Motivation

It will be useful to have builtin metric source with jvm memory usage stats.

Definition of Done

It must expose the following metrics as a separate gauge metric each:

• heap memory usage (init/used/commited/max)
• non-heap memory usage (init/used/commited/max)
• name of metrics should have the general prefix "jvm." to group all future jvm metrics together

Also, it needs to check, if calculation of these stats is heavy and we need to cache it for some time windows.
