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.
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

Concurrent access to the same query module had a race condition on the
pointer that was used to handle the custom memory management. With this
commit, a mapping has been added to keep information about what
thread used the pointer to handle the memory resources. This should be
fine since the respected query executions are running on a dedicated
thread. Access to the mapping itself is threadsafe. A simple RAII
wrapper for the mapping container has also been added for simpler
client-side use.
Add supernode vertex cache to account for long delta chains and modifications in the same module being independent of scanning of the nodes in the next iteration of the pulling mechanism.
