Decoupling Interpreter from Storage (#1186)

Browse Source 
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
