Description of problem:

Occasionally, the e2e-gcp-op-ocl test, TestOnClusterLayering fails intermittently. Specifically, it fails when the rebuild annotation is applied to the MachineOSConfig object. The test fails due to a timeout that occurs, presumably because a new build does not get started.

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

N/A

How reproducible:

Intermittently, with no discernible pattern.

Steps to Reproduce:

Run the e2e-gcp-op-ocl job. It may pass, it may not.

Actual results:

The test fails from a timeout presumably due to the build never starting.

Expected results:

The build should start and the test should pass.

Additional info:

An example of a failing job run may be found here: https://prow.ci.openshift.org/view/gs/test-platform-results/pr-logs/pull/openshift_release/58848/rehearse-58848-pull-ci-openshift-machine-config-operator-master-e2e-gcp-op-ocl/1867557658806980608.

Also, because the rebuild annotation is supposed to be backported to 4.18 (see: https://github.com/openshift/machine-config-operator/pull/4717), any fix for this will likely also require a backport as well.
