Make it possible to replay the full query logs from
CASSANDRA-13983 against one or several clusters. The goal is to be able to compare different runs of production traffic against different versions/configurations of Cassandra.
- It should be possible to take logs from several machines and replay them in "order" by the timestamps recorded
- Record the results from each run to be able to compare different runs (against different clusters/versions/etc)
- If fqltool replay is run against 2 or more clusters, the results should be compared as we go
