* Add CREATE, START, STOP and DROP queries
* Fix definition of port in replica query
* Explicitly stop the consumer before removing
* Fix offset committing in Consumer
* Add tests for basic stream queries
* Remove unnecessary WITH keywords from CREATE query
* Add tests
* Add STREAM privilege
* Disable not working test
The functionality is tested manually, but I couldn't make it work with
the mock kafka cluster.
* Add support for multiple topic names
* Replace skiplist by synchronized map
* Make Consumer::Test const and improve error handling
The improvement in the error handling is mostly done regarding to the
Test function. Instead of trying to revert the assignments, Test just
stores the last commited assignment. When Start or Test is called, they
check for the last commited assignments, and if it is saved, then they
try to restore it. This way:
1. All the failures are returned to the user (failed to save/restore)
2. Failed assignment cannot terminate Memgraph
* Make Test do not block creating/droping other streams
This PR introduces READ COMMITTED and READ UNCOMMITTED isolation levels.
The isolation level can be set with a config or with a query for different scopes.
* Add LOAD CSV clause infrastructure
* Add LoadCsv operator
* Update csv::Reader class
* Support csv files with and without header

Summary:
Switching to Storage V2 API will require passing storage::View when
serializing VertexAccessor and EdgeAccessor, so this is just the first
step in adapting the code.

Summary:
This makes Gid the same as the one in storage/v2. Before they can be
merge into one implementation, we probably want to have a similar
transition for remaining ID types.

Summary:
This diff splits single node and distributed storage from each other.
Currently all of the storage code is copied into two directories (one single
node, one distributed). The logic used in the storage implementation isn't
touched, it will be refactored in following diffs.
To clean the working directory after this diff you should execute:
```
rm database/state_delta.capnp
rm database/state_delta.hpp
rm storage/concurrent_id_mapper_rpc_messages.capnp
rm storage/concurrent_id_mapper_rpc_messages.hpp

Summary:
Session specifics have been move out of the Bolt `executing` state, and
are accessed via pure virtual Session type. Our server is templated on
the session and we are setting the concrete type, so there should be no
virtual call overhead. Abstract Session is used to indicate the
interface, this could have also been templated, but the explicit
interface definition makes it clearer.
Specific session implementation for running Memgraph is now implemented
in memgraph_bolt, which instantiates the concrete session type. This may
not be 100% appropriate place, but Memgraph specific session isn't
needed anywhere else.
Bolt/communication tests now use a dummy session and depend only on
communication, which significantly improves test run times.
All these changes make the communication a library which doesn't depend
on storage nor the database. Only shared connection points, which aren't
part of the base communication library are:
* glue/conversion -- which converts between storage and bolt types, and
* communication/result_stream_faker -- templated, but used in tests and query/repl
