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.

* Tracking of Memtable -> SSTable flushes in Mutation Journal segments
* Replay of Mutation Journal segments that were not fully flushed to SSTables
* Distinguish between CommitLog and MutationJournal offsets
* Effectively adds support for node bounces

Rate limit password changes
Introduces property cassandra.role_password_update_interval_in_ms, with default value of 5000.
Logging added when passwords on roles are changed or are rate-limited.

Add an implementation of isExpired to ReusableLivenessInfo, before the change the method implementation was interited from an interface and always returned false, so livenessInfo().supersedes(...) did not work properly.

Rewrites ANN search query execution logic to more efficiently merge graph search results using
similarity score-ordered (descending) iterators to merge segments efficiently. Allows for reduced memory
consumption during queries, reduced impact of overwrites and tombstones, selective re-querying of
minimally necessary graphs, and reduced shuffling of PrimaryKey objects.

Make MemoryUtil.clean() throw for slices/duplicates that cannot be cleaned and fix mmap cleanup
Parameterise main compaction tests for cursor/iterator and buffered/direct combinations
patch by Sam Lightfoot; reviewed by Ariel Weisberg, Dmitry Konstantinov for CASSANDRA-21147
This is a partial solution to IllegalStateException thrown by VectorPostings. It works by using a single shard at L0 when a vector index is present. As noted in the jira ticket, there are edge cases that may still produce errors, notably the case where there are multiple data directories.
The key trade offs here are related to the time complexity for search. Since graph search is log(n), and searching m graphs is m * log(n), we see better search performance by building bigger graphs which is essentially log(m * n). We could pre-shard, which comes at a cost of increased search time complexity.

Introduce the ability to override compaction strategy for specific keyspaces
and tables at startup via two new system properties:
- cassandra.override_compaction.entities: comma-separated list of keyspaces
and keyspace.table pairs (e.g. "ks1,ks2.tbl1,ks3.tbl2")
- cassandra.override_compaction.params: JSON compaction parameters to apply
