Xenial: pip_install fails during repo-install.yml

[Michael Gugino]

Xenial AIO fails repeatedly on step repo-install.yml. This is due to pip_install dependency failing with the following error:

    Install required packages for get_url module

    To prevent Ansible get_url module from generating SNI warnings
    several system packages are being installed so that system python
    will allow us to get pip and install it.

    The strategy for using system pip to install the python packages
    to prevent SNI warnings causes additional issues as system package
    pip versions may be broken in spectacular ways which prevent us from
    upgrading to pinned versions of each of pip, setuptools, wheel.

Change abandoned by Jesse Pretorius (odyssey4me) (<email address hidden>) on branch: liberty
Review: https://review.openstack.org/355916
Reason: This isn't working, and the pip install process has changed so much that it's rather a pain to find a good solution. As we have no reports of SNI issues for Liberty, I'll abandon this for now.
