[MORAE] Specific node tests of FN -> Memgraph

[Free-Quarks]

The idea for this test is to use a sample gromet FN and pull the number of nodes from it using a deployed endpoint and then make sure the memgraph version of the FN also has the same number as a sanity check.

This could be done either:

1. We check the query that would be sent to memgraph to count the wires. (Not needing to have memgraph running during test)
2. We query the memgraph graph to count the wires (requires memgraph to be running during test)

This test could be expanded in some dimensions related to metadata. I think initially we will ignore metadata, but could be good to make sure all the metadata is kept through the pipeline.
