b90375c3ae Remove GraphDbAccessor and storage types from Ast
Summary:
This diff removes the need for a database when parsing a query and
creating an Ast. Instead of storing storage::{Label,Property,EdgeType}
in Ast nodes, we store the name and an index into all of the names. This
allows for easy creation of a map from {Label,Property,EdgeType} index
into the concrete storage type. Obviously, this comes with a performance
penalty during execution, but it should be minor. The upside is that the
query/frontend minimally depends on storage (PropertyValue), which makes
writing tests easier as well as running them a lot faster (there is no
database setup). This is most noticeable in the ast_serialization test
which took a long time due to start up of a distributed database.

43cb506f06 Prepare codebase for high availability
Summary:
Initial for fork (in form of a c/p) form the current single node
version. Once we finish HA we plan to re-link the files to the single node
versions if they don't change.

6894e2aef8 Distributed BFS filter lambda
Summary:
TODO:

~~1. Figure out how to propagate exceptions during lambda evaluation to master.~~

~~2. Make some more complicated test cases to see if everything is~~
~~sent over the network properly (lambdas depending on frame, evaluation context).~~

~~3. Support only `GraphView::OLD`.~~

4. [MAYBE] Send only parts of the frame necessary for lambda evaluation.

~~5. Fix EdgeType handling~~

--------------------

Serialize frame and send it in PrepareForExpand RPC

Move Lambda out of ExpandVariable

Send symbol table and filter lambda in CreateBfsSubcursor RPC

Evaluate filter lambda during the expansion

Send evaluation context in CreateBfsSubcursor RPC
