Kill the java module with fire

The java module was only being used by the analytics infrastructure and
wasn't really adopted anywhere else in the tree. Since we deprecated the
use of Sun/Oracle Java across the fleet, the class really boils down to
installing either one of four packages (JRE, JDK x 6, 7) and we don't
really need a class for that.

Convert role::analytics to a simple Package resource and kill the module
altogether both to reduce our LoC/cruft and to stop encouraging the use
of Oracle Java.
