Initial work on i18n. This adds the installation of the nova domain in gettext to all the "endpoints", which are all the bin/* files and run_tests.py.

In addition, we place a small hack in /nova/tests/__init__.py that allows nosetests to run without problems.

The next series of patches will "i18n"-ify the strings in Nova using the _() gettext function.
