The change doesn't handle the case where cfg.py imports other modules
from openstack/common which aren't installed yet either. This is the
case with the new iniparser.py module that I recently got merged.

As a workaround so I can get my changes into nova, I hacked update.py to
use this code:

try:
    from openstack.common import cfg
except AttributeError:
    try:
        sys.path.insert(0, '.')
        from openstack.common import cfg
    finally:
        sys.path.pop(0)

Title:
  openstack namespace does not play nicely with checkedout repos

Status in openstack-common:
  Confirmed

Bug description:
  Both openstack.common and openstack.nose_plugin declare the
  'openstack' namespace. When one package is installed it breaks pythons
  search path of ./ for modules.  This breaks update.py for example
  which is meant to be run out of the os-common checkout directory. It
  imports cfg from openstack.common, but since it is not installed it
  cannot be found:

  
  site-packages$ ls openstack*
  openstack.nose_plugin-0.5-py2.7-nspkg.pth

  openstack:
  nose_plugin.py  nose_plugin.pyc

  openstack.nose_plugin-0.5-py2.7.egg-info:
  dependency_links.txt  installed-files.txt     PKG-INFO      SOURCES.txt
  entry_points.txt      namespace_packages.txt  requires.txt  top_level.txt

  common$ python update.py
  Traceback (most recent call last):
    File "update.py", line 64, in <module>
      from openstack.common import cfg
  ImportError: No module named common

  Since update.py is a "temporary" workaround for incubation we *could*
  hack it to inject ./openstack/common into the openstack namespace, but
  there might be a better way. Need to research.
