WIP [consensus] more metrics for LogCache
This patch adds more debug-level metrics to the LogCache for better
observability (also, I did this in attempt to better understand the
LogCache's main use case).
WIP:
* add test coverage for the newly added metrics
* find a test scenario to see at least 1 hit in the cache -- so far
when playing with `kudu perf loadgen`, no hits were observed
