Gleb Natapov 31e803a36c storage_proxy: wire up percentile speculative read properly ...

Collect coordinator side read statistic per CF and use them in percentile
speculative read executor. Getting percentile from estimated_histogram
object is rather expensive, so cache it and recalculate only once per
second (or if requested percentile changes).

Fixes #2757
