Add a github action to create a kind cluster and run some tests about hydrophone

[rjsadow]

@dims for Run conformance tests. what are you envisioning? Running the entire conformance suite?

[dims]

@rjsadow not on every PR, but periodically

[dims]

using --focus='[Conformance]' should be enough

Periodic test is running (https://github.com/dims/hydrophone/actions/runs/7284630106), however it does exit with a successful return code. I'm gathering that hydrophone is running the test, reporting on the logs of the pod, then exits successfully. This will make any CI tests difficult to determine if there are failures. @dims how do you feel about tying the exit code of hydrophone with the exit code of the pod?

sounds good @rjsadow

#28 didn't work as expected. I'll look into more how we can ensure we bubble up the test status

let's open up fresh issues as we see these @rjsadow - i have some changes in there which should help.
