How to refresh a Snowflake token

If you're using a Snowflake virtual graph and don't want to re-enter credentials every 4 hours to get a new token, you can set the connection pool option maxAge to some value less than 4 hours. Per the Tomcat docs, maxAge is "Time in milliseconds to keep a connection before recreating it." 4 hours is 14,400,000 milliseconds, so set maxAge to a value lower than this for the connection to be recreated before the timeout.
