Hi!

The library is accessible at
https://github.com/aababilov/python-openstackclient-base. I have update it
so it doesn't require monkey patch for nova and keystone clients anymore.

I'm familiar with
python-openstackclient<https://github.com/openstack/python-openstackclient>,
and it will be an awesome tool. But it is a console client, and I am
talking about an API client library. This library can be used by
python-{nova,keystone,glance}client that are used, in their turn, by
python-openstackclient <https://github.com/openstack/python-openstackclient>,
horizon, etc.

I used modified code from glance that does chunking manually. It's worth to
mention that glance client can be simpler - it should not deal with chunkes
anymore. Requred changes for glanceclient are accessible here:
https://github.com/aababilov/python-glanceclient/commit/7b04a1672a4ba09281ea107c47a8b20d9a0c62bb
.

openstack-common seems to be a stub for a server and there is no client
code, isn't it?

Sincerely
