Setup CI test that uses kind in GH actions and perform one (smaller) benchmark.

[bwplotka]

prombench supports kind but we never test it on CI, nor not many use it. To make that path healthy I propose we leverage it to test prombench in general -- to deploy cluster, infra resources and deploy one small benchmark (with reduced amount of metrics), all within 5m timeout on GH Actions. Ambitious? Maybe (:

Acceptance Criteria

• On every PR we will create a tiny kind, deploy all infra resources, and one smaller benchmark and expect all resources to be successful, then tear down.
