how tWAS image/runtime load certificates 

We use Runtime Component Operator (RCO) 1.2 to deploy tWAS image to OCP.  Now RCO supports TLS by default, but RCO does not know about runtime or any language of the apps so it is up to the app developers to handle loading certificate for the Operator to mount to /etc/x509/certs.

This issue is for investigating how tWAS image/runtime load certificates and mount for operator to handle it
