Instascale E2E - Machine Sets

[Fiona-Waters]

WHY

To test Instascale machine set functionality.

WHAT

An end to end test testing Instascale functionality on an OCP cluster - which uses machine sets.

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 machine sets.
