building image is broken due to pip 8.0

[Craig Vyvial]

Once pip 8.0 was released this caused wide spread issues with openstack and there is an effort to clean this up.

Once i identified where we had an issue i have 2 options.

1. remove heat-cfntools from the dependencies for the image
2. wait and get a few patches merged.
  a. heat-cfntools remove argparse from requirements
  b. push a new version of heat-cfntools
  c. also need the tripleo-image-elements updated with pip 7.1.3

Fix proposed to branch: master

so heat-cfntools released a fix and pip 8.0.1 also was released to fix the issues that everyone was seeing. The final issue is with tripleo-image-elements and this should be ratified by the latest changeset of this patch.

    Adds the dib elements before the triplo elements

    There is a duplicate package of pip-and-vitrualenv in dib elements as
    well as in triple-image-elements. Adding the dib elements before the
    tripleo elements in the ELEMENTS_PATH environment variable will allow
    dib to find its own element first instead of the of tripleo
    element. The tripleo element for pip-and-virtualenv need an update to
    work right. This will make sure that we are using the common set of
    elements before the tripleo elements in the future.
