feat: added integration tests to cover evicted pods in post conditions

[Al-Pragliola]

Tracking issue: RHOAIENG-15614

Description

Seeing that testing in a real cluster can be quite problematic, I added integration tests to cover scenarios with evicted pods, I didn't add a negative test because it takes 5 minutes to fail and the timeout duration is not configurable.

How Has This Been Tested?

i guess here is
It("should succeed when expected pod in the namespace is ready", func(ctx context.Context) {

[zdtsw]

otherwise, i am fine with the change

[Al-Pragliola]

condition feature.WaitForPodsToBeReady will be satisfied only if all pods in the namespace are "Ready", in the test case there's only one pod but "should succeed when all pods in the namespace are ready" should still be valid, I can add more pods in the test if you think is necessary
