eb4e2b019d Fix distinct, now doesn't impacts other aggregates (#1235) 
Before a distinct on one aggregate would impact distinct on another
aggregate. Fixed the logical error and at the same time did some memory
optimisations.

bce48361ca Decoupling Interpreter from Storage (#1186) 
Unique/global InterpreterContext that is Storage agnostic (has a reference to the DbmsHandler instead)

* InterpreterContext is no longer the owner of Storage
* New Database structure that handles Storage, Triggers, Streams
* Renamed SessinContextHandler to DbmsHandler and simplified the multi-tenant logic
* Added Gatekeeper and updated handlers to use it

9661c52179 Introduce a reader writer spin lock (#1187) 
It is possible for multiple read only queries to be accessing the same
sequence of vertices/edges. The reader mode of the spin lock will ensure
multiple threads can make progress at the same time.

5f509532f2 Add timestamp to DELETE_DESERIALIZED_OBJECT delta at which this object was created. (#1179) 
Add timestamp to DELETE_DESERIALIZED_OBJECT delta at which this object was created.
RocksDB currently doesn't provide timestamp() functionality in iterators of TransationDB.
Because of that we are using constant "0" timestamp for DELETE_DESERIALIZED_OBJECT.
