Look at using a pool connection in `TopologyChangeListener`

[pietermartin]

Currently TopologyChangeListener creates a new connection using Connection connection = DriverManager.getConnection(jdbcUrl, props);
This change occurred #488

It does not use the pool connection as this is a very long running connection and some pools will evict such connections.

However on AWS the password is no longer available to create a new connection, so we need to come up with an alternative.

@gustavo-armenta how can Sqlg access the password? Are you sure the pool will not evict the connection after some time?

I figure out how to create aws iam role token and pass it in the jdbc.password property. Tested and it worked ok
