Subject: Add assignment list to v2 identity and deprecate alternate listing

The current identity role list command (both v2 and v3) is
overloaded with listing roles as well as assignments (if you
provide user, group, project or domain options). This is in
addition to the v3 assignment list command designed for this
purpose.

This overloading complicates the fact that roles can now be
domain specific (i.e. have a domain attribute), so the
command 'role list --domain <domain-name' will soon become
ambigious (this is in a follow on patch).

This patch:

- Adds a v2 assignments list, with support for pulling the
user and project from the auth credentials
- For comapability, adds the same auth support to the
existing v3 assignments list
- Deprecates the use of role list and user role list to list
assignments
