Allow individual extras selection (#3080)

* Allow individual extras selection

Currently networkx only has a definition for "all" dependency extras.
This patch adds support to specify the individual extras required.

Our use case is for pydot where we use nx_pydot but none of the other
"extras".

* Added missing 'nose' extra
