d4f0bb0e38 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

e2e7823ec4 Add basic support for unique constraints in storage 
Summary:
This diff contains a basic implementation of unique constraints consistent with
the MVCC storage.
Stale records in the unique constraints are collected by the garbage collector.
Tests for checking correctness of unique constraints and violations are included.
Note: currently we only support a pair of label and a single property. Support for
multiple properties will be added later.

10cc831ed2 Implement all edge filters for storage v2 
Summary:
Edge filters (edge type and destination vertex) are now handled natively in the
storage API. The API is implemented to be the fastest possible when using the
filters with the assumption that the number of edge types will be small.

9e04183be7 Implement query execution timeout 
Summary:
The query execution now has a timeout for each Cypher query it executes. The
timeout is implemented using TSC and will work only when TSC is available (same
as PROFILE). TSC is used to mitigate the performance impact of reading the
current time constantly.
