* 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

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
Summary:
Now when iterating over a label+property index the index verifies that the
bounds meet the criteria imposed by openCypher.

Summary:
There's a possible race condition where we add a deleted vertex into
index and garbage collection removes it from main storage before indices are
cleaned-up.
