0.4.0

Breaking changes

• We have changed behavior of .get_metadata method. It now returns an
  instance of Metadata class. Method .inspect is meant to return raw data
  of the selected backend.

New Features

• Introduction of a new class to hold container and image
  metadata.
  In coming weeks, we'll be working on integrating this class into the library.
  Our main intent is to make the Metadata class generic across all backends.

• conu now has an API to access image layers (#207)
• We've added Contribution guide, thanks to Rado Pitonak (#208).

Fixes

• Provide docker container filesystem using docker export instead of atomic mount — conu no longer requires
  atomic. This also means that root
  privileges are no longer required.
• Don't depend on enum34 for python 3, thanks to Rado Pitonak (#214)
