Added support for client defined result data in FReeIPABaseModule

Modified support for processing result of IPA API commands so that
client code can define its own processing and add return values to
self.exit_args based on command result.

If a subclass need to process the result of IPA API commands it should
override the method `process_command_result`. The default implementation
will simply evaluate if `changed` should be true.
