ifupdown: add new ifupdownflags class to carry ifupdown flags

Browse Source 
Ticket: cleanup
Reviewed By:
Testing Done: Tested ifupdown sanity

This gets rid of some ugly previous flag handling which was
passed through modules. This creates a global instance of
flags that all addon modules and helper modules can use.
