scheduler: add metrics to equivalence cache

This adds counters to equiv. cache reads & writes. Reads are labeled by
hit/miss, while writes are labeled to indicate whether the write was
discarded.

This will give us visibility into,
- hit rate of cache reads
- ratio of reads to writes
- rate of discarded writes
