Instascale E2E - Node Pools

[Fiona-Waters]

WHY

To test Instascale node pool functionality (To follow on from this PR)

WHAT

An end to end test testing Instascale functionality on a Hypershift cluster - which uses node pools.

HOW

WIP PR. For now, these tests would assume that you already have an OpenShift cluster spun up and configured correctly for InstaScale functionality. A follow-on to this will be running the tests in CI.

TESTS

N/A

DONE

An e2e test exists that tests Instascale functionality for scaling node pools.
