Add coverage reporting via codecov

[blueyed]

TODO:

• [ ] should not be used for all jobs probably, but only cover different variants (py2, py3, and one of py27-django{1.8,1.9}-drf{3.1,3.2,3.3,3.4} (which installs djangorestframework-oauth==1.0.1).

@jpadilla djangorestframework-oauth is only supported for py27? Is it necessary for it to cover / test it?

[blueyed]

See the report at: https://codecov.io/gh/GetBlimp/django-rest-framework-jwt/pull/382/tree

I would like to have this before doing any other cleanup.

[jpadilla]

Regarding those oauth tests and what not, I'd say we get rid of them. If I recall we just had those after #4.

@jpadilla Can you please activate/install the codecov integration on https://codecov.io/gh/GetBlimp/django-rest-framework-jwt?

[jpadilla]

@blueyed done!
