Description of problem:

Some of the PIS regression tests do not appear to be running as intended. For example, the `Invalid PIS leads to degraded MCN in a custom Pool` PinnedImageSet test is consistently only taking ~3 seconds to run "successfully," both when run in isolation locally and in recent payload test runs. This is logically not enough time for the steps of the test, which, at a high level, include creating a custom MCP, adding a node to it, applying a PIS, waiting for the MCN degraded PIS condition to be true, and then returning the cluster to its pre-testing state. Similar behavior has been seen in an original investigation of the `All Nodes in a Custom Pool should have the PinnedImages in PIS` test. In this test, the custom pool never becomes updated with one ready machine.

Version-Release number of selected component (if applicable):

Seen in 4.20, but I have not checked in 4.19.

How reproducible:

Always.

Steps to Reproduce:

Run the `Invalid PIS leads to degraded MCN in a custom Pool` test against a 4.20 cluster and monitor the MCP throughout the run to see no nodes successfully add to the MCP.

Actual results:

So far, it seems like the test fails in the following steps:

• When a node is added to the custom MCP, there is no wait to make sure the node successfully adds.
• It does not seem like the MCN PIS degraded condition is being properly validated.

Expected results:

The PIS test should run as the test name implies.
