looks like some related unit tests are failing.

sorry for the late review here, but spotted a few things of note:

pkg/controller/registry/grpc/source.go
func (s *SourceStore) Add(key registry.CatalogKey, address string) (*SourceConn, error) {
_ = s.Remove(key)

conn, err := grpc.Dial(address, grpc.WithInsecure())
conn, err := grpcConnection(address)

Can we abstract the dial logic away? maybe take a Dailer as a field of SourceStore?

If we pursue this option wouldn't the connection to the proxy need to remain open indefinitely?

nit: We should probably memoize these so we don't fetch them for every dial.

This seems reasonable but would make the values static, which likely isn't a problem given how deployments and pods work.
