So if someone writes an extension / procedure / integration-test that needs apoc, we need to document how they need to setup their java dependencies (maven/gradle) and the code they need to use with neo4j-harness / TestGraphDBService etc. to properly load the apoc procs.

@michael-simons had figure out a while ago how to do that, we can use his example code for that.
