Fix REPLICA timestamps (#1615)
* 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

Refactor interpreter to support multiple distributed clocks (Part 1) (#1281)
* Interpreter transaction ID decoupled from storage transaction ID
* Transactional scope for indices, statistics and constraints
* Storage::Accessor now has 2 modes (unique and shared)

* Split InfoQuery in two: non-transactional SystemInfoQuery and transactional DatabaseInfoQuery
* Replicable and durable statistics
* Bumped WAL/Snapshot versions
* Initial implementation of the Lamport clock

Correct inconsistencies w.r.t. sync replication (#435)
Add a report for the case where a sync replica does not confirm within a timeout:
-Add a new exception: ReplicationException to be returned when one sync replica does not confirm the reception of messages (new data, new constraint/index, or for triggers)
-Update the logic to throw the ReplicationException when needed for insertion of new data, triggers, or creation of new constraint/index
-Add end-to-end tests to cover the loss of connection with sync/async replicas when adding new data, adding new constraint/indexes, and triggers

Add end-to-end tests to cover the creation and drop of indexes, existence constraints, and uniqueness constraints

Improved tooling function mg_sleep_and_assert to also show the last result when duration is exceeded
