Initial checkin for new CLI and client package

Copied mostly from python-keystoneclient with
some Glance-specific stuff. README.rst shows what
WILL be the way to do things, not what is currently coded :)

+Python bindings to the OpenStack Glance API
+=============================================
+
+This is a client for the OpenStack Glance API. There's a Python API (the
+``glanceclient`` module), and a command-line script (``glance``). The
+Glance 2.0 API is still a moving target, so this module will remain in
+"Beta" status until the API is finalized and fully implemented.
+
+Development takes place via the usual OpenStack processes as outlined in
+the `OpenStack wiki`_.  The master repository is on GitHub__.
+
+__ http://wiki.openstack.org/HowToContribute
+__ http://github.com/openstack/python-glanceclient
+
+This code a fork of `Rackspace's python-novaclient`__ which is in turn a fork of
+`Jacobian's python-cloudservers`__. The python-glanceclient is licensed under
+the Apache License like the rest of OpenStack.

+
+By way of a quick-start::
+
+    # use v2.0 auth with http://example.com:5000/v2.0")
+    >>> from glanceclient.v2_0 import client
+    >>> glance = client.Client(username=USERNAME, password=PASSWORD, tenant_name=TENANT, auth_url=KEYSTONE_URL)
+    >>> glance.images.list()
+    >>> image = glance.images.create(name="My Test Image")
+    >>> print image.status
+    'queued'
+    >>> image.upload(open('/tmp/myimage.iso', 'rb'))
+    >>> print image.status
+    'active'
+    >>> image_file = image.image_file
+    >>> with open('/tmp/copyimage.iso', 'wb') as f:
+            for chunk in image_file:
+                f.write(chunk)
+    >>> image.delete()
+
+
+Command-line API
+----------------
+
+Installing this package gets you a command-line tool, ``glance``, that you
+can use to interact with Glance's Identity API.
+
+You'll need to provide your OpenStack tenant, username and password. You can do this
+with the ``tenant_name``, ``--username`` and ``--password`` params, but it's
+easier to just set them as environment variables::
+
+    export OS_TENANT_NAME=project
+    export OS_USERNAME=user
+    export OS_PASSWORD=pass
+
+You will also need to define the authentication url with ``--auth_url`` and the
+version of the API with ``--identity_api_version``.  Or set them as an environment
+variables as well::
+
+    export OS_AUTH_URL=http://example.com:5000/v2.0
+    export OS_IDENTITY_API_VERSION=2.0
+
+Since the Identity service that Glance uses can return multiple regional image
+endpoints in the Service Catalog, you can specify the one you want with
+``--region_name`` (or ``export OS_REGION_NAME``).
+It defaults to the first in the list returned.
+
+You'll find complete documentation on the shell by running
+``glance help``::
+
+    usage: glance [--username USERNAME] [--password PASSWORD]
+                  [--tenant_name TENANT_NAME | --tenant_id TENANT_ID]
+                  [--auth_url AUTH_URL] [--region_name REGION_NAME]
+                  [--identity_api_version IDENTITY_API_VERSION]
+                  <subcommand> ...
