Query allocator and evaluation allocator were different.
After analysis, was determined they should be the same, this will help
future development reduce TypeValue copies during queries.
Changes:
- Common allocator, PoolResource backed by MonotonicResource
- Optimized Pool, now O(1) alloc/dealloc as all chunks in Pool form a single
free list
- 2nd PoolResource, using bin sizing, not as perfect for memory usage but
O(1) bin selection
- Now have jemalloc's background thread to make sure decay and return
to OS happens
- Optimized ProperyValue to be faster at destruction/copy/move
- Less temporary memory allocations
- CSV reader now maintains a common line buffer it reuses on line reads
- Writing out bolt values, now reuses a values buffer
- Evaluating an int no longer makes temporary strings for errors it most
likely never throws
- ExpandVariable will reuse existing edge list in frame it one existed

* Optimise frame change
* Optimise distinct + orderby memory usage
- dispose collections as earlier as possible
- move values rather than copy
* Better perf, ORDER BY
* Optimise RANGE and UNWIND
* ConstraintVerificationInfo only if at least one constraint
* Optimise TypeValue
* Clang-tidy fix
- Remove the e2e that did concurrent mgp_* calls on the same transaction
(ATM this is unsupported)
- Fix up the concurrent mgp_global_alloc test to be testing it more precisely
- Reduce the memory limit on detach delete test due to recent memory
optimizations around deltas.
- No longer throw from hook, through jemalloc C, to our C++ on other
side. This cause mutex unlocks to not happen.
- No longer allocate error messages while inside the hook. This caused
recursive entry back inside jamalloc which would try to relock a
non-recursive mutex.
* Add AUTH system tx deltas
* Add auth data RPC and handlers
* Support multiple system deltas in a single transaction
* Added e2e test
* Bugfix: KVStore segfault after move

* 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

The DoubleToString function has been updated to handle higher precision doubles correctly. The unnecessary string length restriction has been removed, allowing the function to convert the full double value without prematurely truncating it. This change ensures that the string representation of doubles is more accurate, especially for very large or very small numbers. Unit tests have been added to verify the correct behavior for a range of double values.
* Fix up REPLICA GetInfo and CreateSnapshot
Subtle bug where these actions were using the incorrect transactional
access while in REPLICA role. This casued timestamp to be incorrectly
bumped, breaking REPLICA from doing replication.
* Delay DNS resolution
Rather than resolve at endpoint creation, we will instread resolve only
on Socket connect. This allows k8s deployments to change their IP during
pod restarts.
* Minor sonarsource fixes

Single (instance level) connection to a replica (messages from all databases get multiplexed through it)
ReplicationClient split in two: ReplicationClient and ReplicationStorageClient
New ReplicationClient, moved under replication, handles the raw connection, owned by MainRoleData
ReplicationStorageClient handles the storage <-> replica state machine and holds to a stream
Removed epoch and storage from *Clients
rpc::Stream proactively aborts on error and sets itself to a defunct state
Removed HandleRpcFailure, instead we simply log the error and let the FrequentCheck handle re-connection
replica_state is now a synced variable
ReplicaStorageClient state machine bugfixes
Single FrequentCheck that goes through DBMS
Moved ReplicationState under DbmsHandler
Moved some replication startup logic under the DbmsHandler's constructor
Removed InMemoryReplicationClient
CreateReplicationClient has been removed from Storage
Simplified GetRecoverySteps and made safer
