Michael Johnson 8b08d212c3 Fix DIB scripts python version
Now that DIB is python3 only we can remove a hack that made sure
scripts outside the chroot ran with the correct version of python.
This is necessary as python3 does not resolve symbolic links to the
binary like python2.x did, which causes element scripts to fail finding
modules when DIB was run from inside a venv.

This patch does the following:
1. Reverts 9c7b8d1714 which was the
   workaround for mixed python2/3 environments.
2. Updates the scripts to use "python3" instead of "python".

Image building tools for OpenStack
==================================

``diskimage-builder`` is a flexible suite of components for building a
wide-range of disk images, filesystem images and ramdisk images for
use with OpenStack.

This repository has the core functionality for building such images,
both virtual and bare metal. Images are composed using `elements`;
while fundamental elements are provided here, individual projects have
the flexibility to customise the image build with their own elements.

For example::

  $ DIB_RELEASE=bionic disk-image-create -o ubuntu-bionic.qcow2 vm ubuntu

will create a bootable Ubuntu Bionic based ``qcow2`` image.

``diskimage-builder`` is useful to anyone looking to produce
customised images for deployment into clouds. These tools are the
components of `TripleO <https://wiki.openstack.org/wiki/TripleO>`__
that are responsible for building disk images. They are also used
extensively to build images for testing OpenStack itself, particularly
with `nodepool
<https://docs.openstack.org/infra/system-config/nodepool.html>`__.
Platforms supported include Ubuntu, CentOS, RHEL and Fedora.

Full documentation, the source of which is in ``doc/source/``, is
published at:

* https://docs.openstack.org/diskimage-builder/latest/
