Added code to allow insertion of boilerplate into modules to make them able to share lots of code, the result

should be a huge reduction of total ansible source, at a slight cost of difficulty in original module development.

We need to apply this now to all modules, but may need to have some exemptions to things like command, which should
subclass this module.
