Set up authentication in Memgraph

[FrancisTembo]

To set up password authentication for connecting to Memgraph, create a user with a username and password. Once the credentials are set, specify the authentication details as follows when connecting to the database:

AUTH = ("memgraphUser", "memgraphPassword")

with GraphDatabase.driver(URI, auth=AUTH) as client:

I did some testing and I could get the authentication working for the research_index application however I couldn't do the same for the research_index_backend. Ultimately I couldn't populate the database and reverted to an unauthenticated Memgraph instance. This should be addressed when I implement ingestion endpoints in the API since we won't strictly need the research_index_backend.
