Description of problem:

The OnClusterBuild tests running in the MCO disruptive suite do not have a healthy pass rate. This dashboard shows the OCB test 7-day pass rates and clicking into the list of failed runs for each test shows that the tests have been failing for a while.

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

4.20 - I've only monitored tests in 4.20, but it's possible the tests are unstable in other versions also.

How reproducible:

Tests fail often.

Steps to Reproduce:

See this example test run to see 3/5 of the OCB tests failing as they seem to fail consistently on a pod readiness timeout.

Actual results:

The `MCO ocb PolarionID:83140-A MachineOSConfig with custom containerfile definition can be successfully applied`, `MCO ocb PolarionID:77781-A successfully built MachineOSConfig can be re-build`, and `A valid MachineOSConfig leads to a successful MachineOSBuild and cleanup of its associated resources` tests consistently fail on pod readiness timeouts across multiple platforms.

Expected results:

The OCB tests should meet the general 95% pass rate criteria for component readiness.

Additional info:

At the time of creating this bug, the OCB tests have the following 7-day pass rate:
