[Task] Flexible k8s smoketest

[tthvo]

Right now, looks like k8s yaml(s) are hard-coded with default namespace.

https://github.com/cryostatio/cryostat3/blob/32b4f83d85de3f3dbe132a33e1f69f405b05460d/smoketest/k8s/cryostat-service.yaml#L16

We should remove this field so that the deployment namespace can be take from the kube client (i.e. oc or kubectl).

Maybe there is some kompose flag for this, or else there can be an additional generation step to patch the yamls in this way.

@andrewazores Would it be suitable to use Makefile in this project? Just thought it might be cleaner to put subcommand as make targets.

[andrewazores]

Sure, we could do that, though if we're going to replace the smoketest.sh script I would rather spend a bit of time exploring alternatives rather than just defaulting to Makefile. For example, Taskfile.

Oh wow! That tool looks pretty neat! I will have a look into it!

[tthvo]

I guess now that kompose does not add namespace: default to generated k8s yamls. This can be closed?
