RHOAIENG-18848: chore(tests/containers): initial kubernetes/openshift deployment support (#892)

* RHOAIENG-18848: chore(tests/containers): add openshift-python-wrapper dependency

* RHOAIENG-18848: chore(tests/containers): initial test that runs container on openshift/kubernetes

* install local-path provisioner on kubernetes in github actions
* more careful printing of pod status in case `containerStatuses == None`
* sort out how we want to work with privileged/unprivileged client
* only run the new test if we have kubernetes around
* add pod waiting and port forwarding utils

+"""Proxies kubernetes portforwards to a local port.
+
+This is implemented as a thread running select() loop and managing the sockets.
+
+There are alternative implementations for this.
+
+1) Run oc port-forward in a subprocess
+* There isn't a nice way where kubectl would report in machine-readable way the
+  port number, kubernetes/kubectl#1190 (comment)
+2) Use the socket as is, mount a custom adaptor to the requests library
+* The code to do this is weird. This is what docker-py does w.r.t. the docker socket.
+  It defines a custom 'http+docker://' protocol, and an adaptor for it, that uses the docker socket.
+3) Implement proxy using asyncio
+* There are advantages to asyncio, but since we don't have Python asyncio anywhere else yet,
+  it is probably best to avoid using asyncio.
+
+Out of these, the oc port-forward subprocess is a decent alternative solution.
