Dockerfile template has to consume latest liberty base image changes.

In latest liberty release "wget and unzip" utilities removed from the liberty image and these changes needed for the templates to work.

Template

Liberty doc to build application image..

Two issues have to be addressed here one is consume "configure.sh" and remove applying license in the Dockerfile and this should be option in "configure.sh" for customers.
