    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
