Disable plugin from the command line

This adds the --disable-pytest-pytorch command line option (#25), which makes it easier to debug incompatibilites with the vanilla pytest collection.

Support for `OpInfo`'s

This minor release adds support for OpInfo's which are used more and more throughout the PyTorch test suite (#17).

Furthermore @xmnlab helped us to get pytest-pytorch into conda-forge. Installation instruction can be found in the README (#18).

Minor improvements

This release includes two minor improvements:

1. Support for selecting individual test cases if there names are nested, i.e. TestFoo and TestFooBar (#12)
2. Removal of PyTorch as installation requirement (#14)

Initial release

pytest-pytorch is a lightweight pytest-plugin that enhances the developer experience when working with the PyTorch test suite if you come from a pytest background.
