Better auth user/role handling (#1699)
* Stop auth module from creating users
* Explicit about auth policy (check if no users defined OR auth module used)
* Role supports database access definition
* Authenticate() returns user or role
* AuthChecker generates QueryUserOrRole (can be empty)
* QueryUserOrRole actually authorizes
* Add auth cache invalidation
* Better database access queries (GRANT, DENY, REVOKE DATABASE)

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

* Replicable and durable statistics
* Bumped WAL/Snapshot versions
* Initial implementation of the Lamport clock

Decoupling Interpreter from Storage (#1186)
Unique/global InterpreterContext that is Storage agnostic (has a reference to the DbmsHandler instead)

* InterpreterContext is no longer the owner of Storage
* New Database structure that handles Storage, Triggers, Streams
* Renamed SessinContextHandler to DbmsHandler and simplified the multi-tenant logic
* Added Gatekeeper and updated handlers to use it
