Subject: Use osc-lib and set up deprecation warnings

The initial use of osc-lib is behind the compatibility/deprecation
modules that we will leave in place for a time for plugins to catch
up.

* openstackclient.common.exceptions
* openstackclient.common.utils

Module-level warnings are emitted directly on stderr since logging
has not been configured yet.
