Use a bbclass to remove argparse from requirements

argparse is required by some of the CLI applications of openstack. The
module is provided by python 2.7, however python-distribute (used in
fido), is not able to find it:

Python 2.7.9 (default, Oct 27 2015, 18:12:55)
[GCC 4.9.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pkg_resources
>>> pkg_resources.get_distribution('argparse')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File
"/usr/lib/python2.7/site-packages/distribute-0.6.49-py2.7.egg/pkg_resources.py",
line 338, in get_distribution
    if isinstance(dist,Requirement): dist = get_provider(dist)
  File
"/usr/lib/python2.7/site-packages/distribute-0.6.49-py2.7.egg/pkg_resources.py",
line 217, in get_provider
    return working_set.find(moduleOrReq) or require(str(moduleOrReq))[0]
  File
"/usr/lib/python2.7/site-packages/distribute-0.6.49-py2.7.egg/pkg_resources.py",
line 698, in require
    needed = self.resolve(parse_requirements(requirements))
  File
"/usr/lib/python2.7/site-packages/distribute-0.6.49-py2.7.egg/pkg_resources.py",
line 596, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: argparse
>>> import argparse
>>>

This patch adds a class that when inherited will remove argparse from
requirements.txt. Also with this patch, those python modules used by
openstackclient inherit the class.
