Ian Wienand 7446c32197 Move diskimage-image-create to an entry point 
It has always been a weird thing that dib is a python package, but
is totally driven by the disk-image-create script.  It creates this
strange division that is hard to explain.

This moves disk-image-create to a regular python entry-point

Currently, this simply exec()s the original disk-image-create script.

However, we now have a (private) interface between disk-image-create
written in python and the driver shell script.  Here's some things we
could do, for example:

* Argument parsing is generally nicer in Python, and then end result
  is mostly just setting environment variables to flag different things
  in the shell script.  I could see us moving the argument-parsing into
  diskimage_builder.disk_image_create:main() and just setting things in
  os.environ before the exec()).

* I7092e1845942f249175933d67ab121188f3511fd sets IMAGE_ELEMENT_YAML in
  disk-image-create by calling-back to element-info.  We can just call
  element_dependencies.find_all_elements() in here an export is to
  os.environ before disk-image-create starts.

* remove need for ramdisk-image-create symlink by just exporting
  IS_RAMDISK based on sys.argv[1] value

* you could even unit test some of this :)

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=trusty disk-image-create -o ubuntu-trusty.qcow2 vm ubuntu

will create a bootable Ubuntu Trusty 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 that are responsible for building disk images. They are also used extensively to build images for testing OpenStack itself, particularly with nodepool. Platforms supported include Ubuntu, CentOS, RHEL and Fedora.
