* Interpreter transaction ID decoupled from storage transaction ID * Transactional scope for indices, statistics and constraints * Storage::Accessor now has 2 modes (unique and shared) * Introduced ResourceLock to fix pthread mutex problems * Split InfoQuery in two: non-transactional SystemInfoQuery and transactional DatabaseInfoQuery * Replicable and durable statistics * Bumped WAL/Snapshot versions * Initial implementation of the Lamport clock --------- Co-authored-by: Andreja Tonev <andreja.tonev@memgraph.io>
