FeeHistogram was being recomputed from scratch on every mempool.sync call. This was unnecessary. Instead we can mutate the existing histogram state for each new transaction added or removed from the mempool.

Extracted from #970. This PR is a prereq of #970.
FeeHistogramwas being recomputed from scratch on every call toMempool::sync. This was unnecessary. Instead we can mutate the existing histogram bin state once on each new transaction added to or removed from the mempool.Prometheus mempool metrics are only updated once per bin at the end of every sync.
