Add basic testing framework for gke-networking-recipes

[songrx1997]

This PR creates a testing framework which will handle the following for future recipe prow tests:

1. Set up a GCP project for the tests (through boskos when running in Prow)
2. Create a GKE cluster
3. Set up Kubernetes clients for the cluster
4. Delete the cluster after tests
5. Add a script the run the test

Hi,

Is the review on this urgent ? Can it wait few weeks ?

Please split the automatic code updates (e.g. go mod vendor etc) from the human changes into separate commits. If you can setup a session (10 minutes) to walk through and demo the tests, that would be useful...

Hi @bowei , just addressed your comments. Could you review this? Thanks

[bowei]

Generally the change looks good. Ping when the comments are resolved.

Seems like some lint rules failed for links in vendor not found. Can we ignore these checks for /vendor?

[bowei]

Can we fix the doc linting OR state explicitly that it won't pass and why. Otherwise looks ok.

Hi @bowei, just removed all the .md files in vendor. All checks passed.

I think the solution is not the delete the files but to ignore the files in vendor/ from the lint....

@songrx1997 -- can you trigger a new test run to check that we got rid of the markdown errors?
