Github Actions use Google Credentials

[AdamMagaluk]

To avoid an issue with google go sdk leaking goroutines we need to ensure it has a proper credential file which avoids it looking up metadata from the GCE metadata endpoints.

Fixes: RSDK-526

See: googleapis/google-cloud-go#5430

This PR currently contains the test code pointing test.yaml to this branch. Once tests pass on the first run i'll update PR to remove that.
