* New Database structure that handles Storage, Triggers, Streams
* Renamed SessinContextHandler to DbmsHandler and simplified the multi-tenant logic

sequence of vertices/edges. The reader mode of the spin lock will ensure
multiple threads can make progress at the same time.

* 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.
