Added a csv writer using the 'csv' library to format properly exported data - escaping, encoding etc. Added a HttpResponse-based class to handle csv generation Added translation for the CSV columns and template. Fix bug #1158383 Renamed few occurencies of 'tenant' to 'project'. Also added a new 'project' in nova_data.py, which required some refactoring of few tests, that didn't consider the current project for project-based calls. Note: I've added a StreamingHttpResponse example, which is introduced in Django 1.5+ and being advised in the ticket. However, my opinion is that at the moment we don't need this - it is too complicated for the current usage. Change-Id: I18bd70a23b7b8389c7c0f96dbf8794fea5e1e75b
