This adds a useful error message when a user enters an invalid value
for --os-image-api-version. Previously, the shell directly attempted to
import the module the user specified, and printed the error from the
exception raised when that failed:
$ glance --os-image-api-version stupid-glance-version
No module named vstupid-glance-version.shell
Glanceclient now catches this exception and prints something
understandable for a user:
$ glance --os-image-api-version stupid-glance-version
"stupid-glance-version" is not a supported API version. Example values are "1" or "2".

Python bindings to the OpenStack Images API ============================================= This is a client library for Glance built on the OpenStack Images API. It provides a Python API (the ``glanceclient`` module) and a command-line tool (``glance``). This library fully supports the v1 Images API, while support for the v2 API is in progress. Development takes place via the usual OpenStack processes as outlined in the `OpenStack wiki <http://wiki.openstack.org/HowToContribute>`_. The master repository is on `GitHub <http://github.com/openstack/python-glanceclient>`_. See release notes and more at `<http://docs.openstack.org/developer/python-glanceclient/>`_.
