maistra TP11 Plugging in external CA key and certs not working

Plugging in external CA key and certs test fails on OCP4.1 AWS. The failed task is:
https://istio.io/docs/tasks/security/plugin-ca-cert/

After user edit the citadel deployment and compare certs, test result shows certs are not the same. It looks like new certs are not mounted on the proxy or not propagated to the pod after citadel redeployment.

In TP10, this test case works fine.
