Description of problem:
Configuring mTLS on default IngressController breaks ingress canary check & console health checks which in turn makes the ingress and console cluster operators into a degraded state.

OpenShift release version:
OCP-4.9.5

Cluster Platform:
UPI on Baremetal (Disconnected cluster)

How reproducible:
Configure mutual TLS/mTLS using default IngressController as described in the doc(
https://docs.openshift.com/container-platform/4.9/networking/ingress-operator.html#nw-mutual-tls-auth_configuring-ingress
)

Steps to Reproduce (in detail):
1. Create a config map that is in the openshift-config namespace.
2. Edit the IngressController resource in the openshift-ingress-operator project
3.Add the spec.clientTLS field and subfields to configure mutual TLS:
~~~
apiVersion: operator.openshift.io/v1
kind: IngressController
metadata:
name: default
namespace: openshift-ingress-operator
spec:
clientTLS:
clientCertificatePolicy: Required
clientCA:
name: router-ca-certs-default
allowedSubjectPatterns:

• "^/CN=example.com/ST=NC/C=US/O=Security/OU=OpenShift$"
  ~~~
  Actual results:
  setting up mTLS using documented steps breaks canary and console health checks as clientCertificatePolicy is set as Required these health checks are looking for the client Certs and hence failing and in turn Ingress and Console operators are in a degraded state.

Expected results:
mTLS setup should work properly without degrading the Ingress and Console operators.

Impact of the problem:
Instable cluster with Ingress and Console operators into Degraded state.

Additional info:
The following is the Error message for your reference:
The "default" ingress controller reports Degraded=True: DegradedConditions: One or more other status conditions indicate a degraded state: CanaryChecksSucceeding=False (CanaryChecksRepetitiveFailures: Canary route checks for the default ingress controller are failing)
