Create e2e tests for new NRO related information collected in must-gather-pao

[jlojosnegros]

We needed to collect new must-gather data related to NRO.
After some discussion it was decided to do it in the must-gather-pao. openshift-kni/performance-addon-operators#919

Now we need to run some e2e tests to ensure it works properly.

As this needs NRO to be installed in the test environment these tests should run in NRO CI and should run nightly or weekly.

I was wondering how could we test this.
I have thought in creating a new test that will create NRO and SCHED and then somehow run the PAO script and check at least the existence of some files.

My problem is I don't really know how to execute a PAO script from the NRO tests.

I think for a e2e test you should just consume the pre-built PAO MG image.
The main complication is making sure you have the oc binary available (but this can be addressed at lane configuration stage I believe). other than that it's about running an external command and checking the result.
Maybe check you have it when the test runs (handling the error if not -> fail the test - or skip? your call)
