Change CacheMetrics to be quicker
...
We change it so that each cache has an individual CacheMetric, instead
of having one global CacheMetric. This means that when a cache tries to
increment a counter it does not need to go through so many indirections.

Manually run GC on reactor tick.
...
This also adds a metric for amount of time spent in GC.
