New GC metrics (in addition to the existing ones)
| Job-/TaskManager | Status.JVM.GarbageCollector | <GarbageCollector>.TimeMsPerSec | Milliseconds spent performing garbage collection per second. | Meter |

| Total.Time | The total time spent performing garbage collection across all collectors. | Gauge | ||
| Total.TimeMsPerSec | Milliseconds spent performing garbage collection per second across all collectors. | Meter | ||
| Total.Count | The total number of collections that have occurred across all collectors. | Gauge |
