New data source: google_compute_instance_template

[ghost]

This issue was originally opened by @universalvishwa as hashicorp/terraform#19663. It was migrated here as a result of the provider split. The original body of the issue is below.

---

Current Terraform Version

Terraform v0.11.10

Use-cases

As a workaround for the following issues,
#1601
hashicorp/terraform#11905

If there was a data source which I can query for an exist instance template I can refer to it in my instance group terraform resource. Then I can avoid having to recreate the instance template in one terraform run. I can separate it from that instance group.

I think this is a very important data source for Google cloud in general.

Expected result: a data source

data.google_compute_instance_template

Attempted Solutions

I've tried to get the instance template self_link by running it inside a local-provisioner of the instance groups resource. But, it's not working not as seamless as I expected it.

Proposal

Please create a data source to query existing data sources in GCP projects.
I've seen that there was some other who have asked for this in the past.
