Please add support for GCP AlloyDB connector similar to Cloudsql Proxy.

Hi @jinlinux ,

The provider allows to use GoCloud to connect to a GCP instance through SQL proxy.
Would it be enough for your needs?

FWIW GoCloud doesn't support AlloyDB yet, but there's a open issue to add that: google/go-cloud#3241
