deploy-gcp script does not enable compute-engine API

When running the deploy-gcp script, the terraform template does not check or enable the Compute Engine API on the project, causing the deployment to fail. If this is API is required it should probably be added to either the instructions or the terraform spec.

@prasvelagapudiagility thanks for the feedback. I will investigate if compute API can be automatically enabled.
