Okay, let's take a step back.  What things should be applicable to 2i CFs?  I think we can
categorize as follows:

Should be included in operations on parent CFs, and allowed for standalone operation on 2i
sstables:

# scrub
# upgradesstables
# invalidate[key|row]cache
# cfstats

Stuff that is not very useful on standalone 2i CFs but harmless:
# flush
# getsstables
# rangekeysample

Stuff that we shouldn't support on individual 2i CFs since foot-shooting potential is so high:
# snapshot

> This was begun in CASSANDRA-4063.  We should extend it to scrub as well, and probably
compact since any sane way to do it for scrub should give the other for free.
> Not sure how easy these will be since they go through CompactionManager via StorageProxy.
 I think getValidColumnFamilies could be updated to check for index CFs with "dot notation."
> (Other operations like flush or snapshot don't make sense for 2I CFs in isolation of
their parent.)
