[PATCHv2 0/6] Add option to recurse into submodules

[Stefan Beller <sbeller@google.com>]

v2:
* this applies on sb/reset-recurse-submodules
* grep and push are also respecting submodule.recurse now.
* Brandon seemed to disagree with the first patch as it may
  hurt with his 'RFC repo object' series [1], but I explained
  a possible way out in [2] and Brandon seemed to agree that this
  makes sense offlist. 
  That first patch was changed to include loading the gitmodules file
  in the call to loading the config.

v1:
In a submodule heavy workflow it becomes tedious to pass in
--recurse-submodules all the time, so make an option for it.

Thanks,
Stefan
