Changelog for 0.9.0

- ARA is now hosted by the OpenStack project community infrastructure.
  - ARA's source code is now available at:
    https://git.openstack.org/cgit/openstack/ara
    or mirrored at
    https://github.com/openstack/ara
  - Submitting patches is now done through OpenStack's Gerrit
    system.
    Documentation on how to contribute is available at
    http://ara.readthedocs.io/en/latest/contributing.html
  - Unit and integration testing is no longer done through
    Travis but instead by OpenStack Zuul testing infrastructure.

- UI Revamp: First implementation
  This is the first release in which lands a first implementation of
  a large UI revamp with the Patternfly [1] CSS framework. There are
  some small issues and quirks but we will iterate in order to fix
  them.

- Playbook file storage
  ARA now stores a unique, zipped copy of playbook files allowing you
  to see the content of your task files as they ran in a particular
  ansible-playbook run. The UI leverages that feature and also provides
  a direct link with line highlight to show where a particular action
  took place.
