Replication refactor part 7 (#1550)
* Split queries into system and data queries
* System queries are sequentially executed and generate separate transaction deltas
* System transaction try locks for 100ms
* last_commited_system_ts saved to DBMS durability
* Replicating CREATE/DROP DATABASE
* Sending a system snapshot if REPLICA behind
* Passing a copy of the gatekeeper::access as std::any to all functions that could call an async execution
* Removed delete_on_drop flag (we now always delete on drop)
* Using UUID as the directory name for databases
* DBMS durability update (added versioning and salient information)
* Automatic migration from previous version
* Interpreter can run some queries without a target database
* SHOW REPLICA returns the status of the currently active DB
* Returning UUID instead of db name in the RPC responses
* Using UUIDs for database specification in RPC (not name)
* FrequentCheck forces update on reconnect
* TimestampRpc will detect if a replica is behind, and will update client's state
* Safer SLK reads
* Split SHOW DATABASES in two SHOW DATABASES (list of current databases) and SHOW DATABASE a single string naming the current database
