* Fix Explain queries
* Add Vertex/Edge accessor support for properties
* Fix projections
* Fix expansions to fetch destination vertex properties
* Fix improper use of ShardMap on bolt and replaced it with the ShardRequestManager
* Add NameToId mappers on ShardRequestManager
* Add e2e tests for operators
* Fix OPTIONAL MATCH
ScanVerticesrequest was not able to utilize filtering capabilities
before. With these modification it is now able to filter the scanned
vertices based on the filter_expressions field in the
ScanVerticesRequest message type.
The communication between the ShardRequestManager and the RsmClient
used to be direct. In this PR this changes into a future-based
communication type. The RsmClient stores state about the currently
processed future (either read or write request) and exposes blocking
and non-blocking functionality to obtain the filled future. The
ShardRequestManager -for now- will send of the set of requests present
in the ExecutionState and block on each of them until the requests are
completed or the set of paginated responses(caused by, for example the
batch-limit in ScanAll) are ready for the next round.
* Use query-v2 in the main executable
* Set up machine manager in memgraph
* Add `ShardRequestManager` to `Interpreter`
* Make vertex creation work
* Make scan all work
* Add edge type map in shard request manager
* Send schema over request
* Empty out DbAccessor
* Store shard mapping at creation
* Remove failing CI steps

Create shard-side handlers for basic messages
Implement the handlers for CreateVertices, CreateEdges and ScanAll. Use
or modify the defined messages to interact with individual Shards and
test their behavior. Shard is currently being owned by ShardRsm
instances. The two top level dispatching functions Read() and Apply()
are responsible for read- and write operations respectively. Currently
there are a handful of messages that are defined but not utilized, these
will be used in the near future, as well as a couple of handler
functions with empty implementations.
