Pin argparse for idempotent pip installs

Argparse is part of the Python standard library in 2.7 but is still
an unmarked and unpinned downstream dependency of some packages
(unittest2==1.1.0 for example).

Ubuntu's libpython2.7-stdlib package includes an argparse.egg-info file
setting its version to 1.2.1.

The python_venv_build process will try to build and install the latest
version of argparse available in PyPI, 1.4.0, but this will never
actually install over the existing standard library install. The pip
module currently marks the install as changed regardless, causing a
restart of OpenStack services during every playbook run.
