hide refresh and access tokens from being logged in datadog

## Description
Currently all the DB commands are being logged in datadog which include access tokens and refresh tokens. If Datadog is compromised then that would put these at risk as well.

## Proposed Solution
Maybe hash/hide the tokens from the logs?
