-----------------------------------------
This looks good for trunk (just waiting on ASF git mirroring to come back up and i'll commit it).

> While bootstrapping new nodes it can take a significant amount of time to catch up on compaction or 2i builds. In these cases it would be convenient to have a nodetool command that allows changing the number of concurrent compaction jobs to the amount of cores on the machine.
> Alternatively, an even better variant of this would be to have a setting "bootstrap_max_concurrent_compactors" which overrides the normal setting during bootstrap only. Saves me from having to write a script that does it.
