Up until now I didn't see the point of using spaces for indentation. However, the previous commit (a18bec3) was quite eye opening. Given that python is an indentation aware language, the amount of mistakes that went unnoticed because tabs and spaces were used at the same time (tabs for indentation and spaces for alignment) were unacceptable. E101,W191 have been re-enable in the tox flake8 checker and the documentation has been modified accordingly. The following files have been left as-is: * bootstrapvz/common/assets/extlinux/extlinux.conf * bootstrapvz/common/assets/init.d/expand-root * bootstrapvz/common/assets/init.d/generate-ssh-hostkeys * bootstrapvz/common/assets/init.d/squeeze/generate-ssh-hostkeys * bootstrapvz/plugins/docker_daemon/assets/init.d/docker * bootstrapvz/providers/ec2/assets/bin/growpart * bootstrapvz/providers/ec2/assets/grub.d/40_custom * bootstrapvz/providers/ec2/assets/init.d/ec2-get-credentials * bootstrapvz/providers/ec2/assets/init.d/ec2-run-user-data * docs/_static/taskoverview.coffee * docs/_static/taskoverview.less * tests/unit/subprocess.sh
