The internal GCP package used `pkg.go.dev/google.golang.org/api` [1] to
interact with Compute Engine API. Modify the package to use the new and
idiomatic `pkg.go.dev/cloud.google.com/go` [2] library for interacting
with the Compute Engine API. The new library have been already used to
interact with the Cloudbuild and Storage APIs. The new library was not
used for Compute Engine since the beginning, because at that time, it
didn't support Compute Engine.
Update go.mod and vendored packages.

Because of the way the gcp secrets are stored for the workers, and how
the mapping from vault to openshift works (unable to map a multiple key
secret into a single json file), there's a bit of juggling required to
get the gcp credentials in the right format.
