Revert "Pre-install pip/virtualenv packages"

This reverts commit a85ce75d6b.

The reason for this revert is because it breaks CentOS dsvm jobs:

http://logs.openstack.org/35/332435/6/check/gate-ansible-role-cloud-launcher-dsvm-ansible-func-centos-7/13b3b66/logs/devstacklog.txt.gz

It is due to DevStack removing python-virtualenv by default, causing issues
as CentOS images have virtualenv installed via system-package and pip
by DIB.

# GENERAL WARNING : mixing packaged python libraries with
# pip-installed versions always creates issues. Upstream
# openstack-infra uses this a lot (especially devstack) but be
# warned: here be dragons :)
# Firstly we want to install the system packages. Otherwise later
# on somebody does a "yum install python-virtualenv" and goes and
# overwrites the pip installed version with the packaged version,
# leading to all sorts of weird version issues.

# pip and setuptools are closely related; we want to ensure the
# latest for sanity. Because distro packages don't include enough
# info in the egg for pip to be certain it has fully uninstalled
# the old package, for safety we clear it out by hand (this seems
# to have been a problem with very old to new updates,
# e.g. centos6 to current-era, but less so for smaller jumps).
# There is a bit of chicken-and-egg problem with pip in that it
# requires setuptools for some operations, such as wheel creation.
# But just installing setuptools shouldn't require setuptools
# itself, so we are safe for this small section.

# Add this to exclude so that we don't install a later package
# over it if it updates. Note that fedora-minimal, bootstrapped
# via yum, can have an old yum.conf around, so look for dnf first.
