Review Comment:
🤔 I think we should have a JMX extension for it and promote it as a first
class citizen in the .yaml. If we end up using this same thread pool for index
building for SASI it's probably something that's going to see _a lot_ more
usage than it is today.
I originally kept it as the very primitive "let's just break the scheduling
coupling" with the suspicion that
https://issues.apache.org/jira/browse/CASSANDRA-11218 would make this work here
moot, however now that I think on it a bit more there's no predicting when and
if that other work will be completed.
