Raphael S. Carvalho 223214439b compaction: Disconsider active tables in the hourly compaction reevaluation ...

This hourly reevaluation is there to help tablets that have very low
write activity, which can go a long time without flushing a memtable,
and it's important to reevaluate compaction as data can get expired.
Today it can happen that we reevaluate a table that is being compacted
actively, which is waste of cpu as the reevaluation will happen anyway
when there are changes to sstable set. This waste can be amplified with
a significant tablet count in a given shard.
Eventually, we could make the revaluation time per table based on
expiration histogram, but until we get there, let's avoid this waste
by only reevaluating tables that are compaction idle for more than 1h.
