shared options and groups

The principle here is to define options once, but *not* instantiate them
globally. One reason being that options with action=&#039;append&#039; can carry state
between parses. pip parses general options twice internally, and shouldn&#039;t
pass on state. To be consistent, all options will follow this design.
