Best effort attempt to get tableId from CFS, fallback to null which, still allows snapshot to be loaded
End result is that nodetool clearsnapshot and listsnapshot function for such snapshots on restart.

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.

Logging added when passwords on roles are changed or are rate-limited.

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.

Legacy Cassandra 3.x sstables use an old bloom filter format that is
incompatible with zero-copy streaming in Cassandra 5.0+. This patch
automatically detects sstables with the old bloom filter format
(pre-4.0) and disables zero-copy streaming for them, allowing legacy
sstables to be loaded via sstableloader without requiring manual flags.
The fix adds a version check in CassandraOutgoingFile.computeShouldStreamEntireSSTables()
that calls descriptor.version.hasOldBfFormat() to detect legacy sstables.

Converting collections or UDTs to raw bytes is nonsensical - it
allows reading raw serialized bytes which have no meaningful
interpretation.

Before the fix during a capacity extension BufferPoolAllocator returned to BufferPool a sliced ByteBuffer wrapper object instead of the originally allocated one, so the ByteBuffer was not recycled by BufferPool
Adjust BufferPoolAllocatorTest to test the ByteBuf capacity extension with a real BufferPool behavior

CASSANDRA-20389 implemented limit on table name length of 222
characters. This commit updates the documentation to reflect this.
It also adds an assert in CreateTableValidationTest to ensure that the
documented limit matches the actual constant.
