Summary: - added only one function for getting the total (in + out) vertex degree, it's required for the Ravelin use-case - specific `degree_in` and `degree_out` functions can be added as necessary - also fixed random_graph_generator bug (needed it for testing) Reviewers: buda, mislav.bradac Reviewed By: buda, mislav.bradac Subscribers: pullbot Differential Revision: https://phabricator.memgraph.io/D652
