Run neo4j and memgraph from run_benchmark script.
This makes mg and neo scripts obsolete.

Summary:
1. Test setup rewritten to take cca 8 seconds. Note that edges are created by using:
`MATCH (a) WITH a MATCH (b) WITH b WHERE rand() < X CREATE (a)-[:ET]->(b)`
Where `X` is a threshold calculated so the desired edge count is the expectation. This seems the only feasable way of generating a large number of edges since query execution does not depend on edge count, but on vertex count.
2. Using the new `assert` function to verify graph state. I recommend doing that in all the harness tests (I don't think we currently have something better).
3. All tests rewritten to take around 200ms per iteration.
4. Test are using SKIP to avoid sending data to the client, but ensure that appropriate operations get executed. This currently seems like the best way of removing unwanted side-effects.
Harness will cost us our sanity. And it doesn't even provide good quality regression testing we really need :(

Summary: It turns out trivial if I use unwind for vertex creation, MATCH for edge creation and UNWIND for test duration. It took hours to converge to this :(

Summary: The previous version didn't seemt to be able to print the operator tree below the `Expand` operator. It seems it was unable to reach the `input_` field because it's a member of the `ExpandCommon` super-type. The proposed fix handles that. @teon, please test, verify, modify, whatever, just ensure printing works below `Expand` operators.

Summary:
This importer is Bolt based. It loads data from Neo and directly injects into
Memgraph. Persistence is optional (JSON based). Currently it works for small
datasets, to make it work for larger datasets batching is required. For it to
work more efficiently indexing on label+property is required (in progress).
An in-Memgraph implementation of JSON importing could be much more efficient,
and is compatible with this script. This sript could be used for exporting
from Neo, and a C++ importer tool for the Memgraph side import.
I suggest that Gradicek takes this over and I can move on to other tasks
I have (if Gradicek is available for this).

Summary:
This is a simple extension to gdb, which will print the LogicalOperator
tree. Auto loading of the extension is supported via .gdbinit if the gdb
is run from the root of the repository.
Explicit loading of scripts can be done inside gdb by running
`source path/to/extension.py`.
