Add a utility to tail logs from kuadrant component pods

I find it useful to have a utility to follow the kuadrant component pod logs, for debugging purposes. Maybe something merging all the pod logs and showing N last lines from it, like https://github.com/stern/stern, or just following them in the second terminal

No files, tests, or entry points are named. Start by locating existing testsuite utilities and how Kuadrant component pods are identified, then clarify whether the utility should merge logs with an N-line limit or simply follow logs for use in a second terminal; done means the chosen behavior works for the component pods.
