Intermittent API requests timeout in OpenShift with x509

Issue

• Experiencing a random kube-apiserver request timeout issue
• Webhook timeouts with an x509 Certificate Signed by Unknown Authority error.

• As an example, sometimes Jenkins pipeline fails during resource GET (services, secrets, deploymentconfig):
