Hello @jcchen2, thanks for your contributions! I think this is looking good! However I do have a few comments:

• if possible I think query logging and ESPECIALLY parameter logging should be toggleable via a setting in the gogm config (that should probably default to off). Parameter logging can lead to nasty vulnerabilities if someone gets access to your logs.
• instead of logging the cypher parameters at each point, injecting that functionality into a session's runReadOnly and runWrite methods would be a bit more elegant and future proof. @erictg any ideas on how to extract the cypher parameters from the runWrite method?

@nikitawootten i created logging wrappers around neo4j's session and transaction. it should be future-proof. i also updated logging to conditionally log parameters. pls let me know what you think.
