1. copied jersey-shiro code to security-jersey module and deleted the files from jersey module

added jersey security module with code borrowed from jersey-shiro

the security stuff is on going work and will be influenced by what shiro does. at some point there will be no dependency on shiro and the security module will be able to stand on its own.
