usage_description="
Lists GCP Cloud SQL databases on each SQL instance in the current GCP Project

Only works on running instances since it requires querying the DB. We skip non-running instances as otherwise the GCloud SDK errors out

Can optionally specify a project id using the first argument, otherwise uses currently configured project
