Create an informative issue (See each section, incomplete templates/issues won't be triaged)

Using the current documentation as a model, please complete the issue template. 

Note: Doc team updates the current version and the two previous versions (n-2). For earlier versions, we will address only high-priority, customer-reported issues for releases in support.

Prerequisite: Start with what we have

1. 1. Cannot access Grafana in OCP 4.16

If the global hub is running in OCP 4.16, the Grafana console cannot be accessed due to the wrong oauth-proxy image. ACM 2.10.4 starts to support OCP 4.16, so that we can get the oauth-proxy from ACM 2.10.4. Here is steps how to workaround:

1. get the correct oauth-proxy image from mch-image-manifest-xxx:

oc get cm -n open-cluster-management mch-image-manifest-xxx -ojsonpath={.data.oauth_proxy_416_and_up} 

2. update the deployment image in global hub csv with the correct one.

oc edit csv multicluster-global-hub-operator-rh.v1.1.1 -n multicluster-global-hub 

Find `RELATED_IMAGE_OAUTH_PROXY` and replace the value with the output of step 1.

Description of problem:

We will have the same issue as described in https://issues.redhat.com/browse/ACM-12455

Since ACM 2.10.4 has supported OCP 4.16 and Global hub 1.1 support ACM 2.10, if the customer upgrades OCP to 4.16 and ACM to 2.10 in FIPs enabled environment, the global hub grafana has issue to open.
