- Make m_earliest_snapshot_ts and m_read_opts protected fields in
Rdb_transaction class. To replace
their previous public uses, introduce new methods get_snapshot_timestamp &
create_explicit_snapshot; use has_snapshot in more places.
Remove unused return value for rdb_tx_acquire_snapshot.
- Factor out Rdb_transaction::on_finish for the common code in on_commit and
on_rollback methods.
- Delete move constructor and move assignment operator for
Rdb_compact_filter_factory class, replace "{}" with "= default" for other
special members.
- Extract the gnarly regexes to make SHOW ENGINE ROCKSDB TRANSACTION STATUS
output deterministic to a separate include file

Temp tables are always private to the owning connection and don't need to participate in isolation concerns
