What this PR does / Why we need it:
Adding terraform template file to create performance test cluster. It's similar to the e2e test cluster terraform template file. But since we are going to create the performance test cluster in a different project, we use a separate template file for it. In future we can combine the performance test cluster template and e2e test cluster template into one file if they are in the same project.

As start, we create one performance test cluster in standard mode and 1.26 (which is the middle version that current agones supports)

Also change the cluster config to VPC-NATIVE mode. The e2e test clusters will be changed to the mode when being re-created.

The cluster is created: https://console.cloud.google.com/kubernetes/clusters/details/us-central1/standard-performance-test-cluster-1-26/details?e=13803378&hl=en&mods=logs_tg_prod&project=agones-e2e-1
