When specifying a single port in port_range, the API would accept it as
input, but would return it as {PORT}-{PORT}. Terraform would then see
this as different, even though (semantically) it's the same.
This commit adds a test that exposes the diff cycle created by this, and
an inline DiffSuppressFunc to resolve it.
Fixes#9051.
Creating most google cloud resources uses the compute_operation to
wait for the creation to complete. However, the computeOperationWait*
functions always uses the global `config.Project`, instead of the resource-
specific one.
This means that creating resource in a project other than the main one
fails with a 404 on the operation resource.
This patch uses the project from google_compute_instance instead of the
global one.
This is the first step in removing the config dependency on "project".
This change is backwards-compatible because the value for this new
attribute defaults to the value from the provider.
