Allow
-o template={{...}}
and-o jsonpath={...}
templates in info so a user can run things like:and extract things from json without a third party command.
Also, fix where oc adm release info supports a default argument implied by the current cluster. If there is a connection error or generic failure we should print the generic message vs the longer error: "info expects one argument, or a connection to an openshift server" instead of "...: unable to contact server ....: connection refused". Print the error at -v=2 instead.
