Run benchmark test on PRs

Fixes #227

• Creates a kind cluster on GH Actions
• Runs install_deps, standup, run (dry run since there is no harness endpoint), and teardown for a facebook/opt-125m model
• Does not create PV and PVCs, does not require hf token, does not use cloud storage

This is pretty good, exactly what we needed. There are some improvements that should be added, such as including pvc creation test, but it can be done later.

Question: how long does it take to create the kind cluster. The whole idea of this particular workflow is to be "as fast as possible", and we can use the pre-deployed cluster already present in benchmark1.yaml to save time.

[jgchn]

The whole workflow takes < 5min (check here). If we can use a pre-deployed cluster, that'd be great. But how would independent users have access to that cluster? I don't think PRs have permission to access secrets defined this workflow. But it's something to explore.

[maugustosilva]

You're correct, accessing the secrets from forks is not possible. LGTM and improve later.
