Blake Eggleston 19be8aeac2 CEP-45: Add mutation tracking support for secondary index reads 
This patch enables mutation tracking for queries using secondary indexes (both
legacy 2i and SAI). Key changes include the addition of the MultiStepSearcher
interface, which allows existing index implementations to iterate over matches
and filter augmented data, proper Memtable snapshotting, and the integration of
these in PartialTrackedIndexRead.

patch by Blake Eggleston; reviewed by Aleksey Yeschenko and Caleb Rackliffe for CASSANDRA-20374
