Code Issues Proposed changes

Use a virtualenv for remote operations by default

Browse Source 
The docker python module fails to install without a virtualenv with
pip10.  The following error is seen in the task Ensure docker SDK for
python is installed:

Cannot uninstall 'ipaddress'. It is a distutils installed project and
thus we cannot accurately determine which files belong to it which would
lead to only a partial uninstall

This is fixed by using a remote Python virtual environment for executing
Kayobe Ansible tasks in the default Kayobe configuration.

@ -132,3 +132,7 @@ If kayobe detects that ``ansible_python_interpreter`` is set and references a
virtual environment, it will create the virtual environment if it does not
exist. Typically this variable should be set via a group variable for hosts in
the ``seed``, ``seed-hypervisor``, and/or ``overcloud`` groups.
The default Kayobe configuration in the ``kayobe-config`` repository sets
``ansible_python_interpreter`` to ``{{ virtualenv_path }}/kayobe/bin/python``
for the ``seed``, ``seed-hypervisor``, and ``overcloud`` groups.

fixes:

Fixes an issue introduced by the release of ``pip`` version 10, whereby the
Python ``docker`` package would fail to install. This is resolved by using
a remote Python virtual environment for executing Kayobe Ansible tasks by
default. See `Story 2002010
<https://storyboard.openstack.org/#!/story/2002010>`__ for details.
