    Support Identity v3 when connecting to Ironic

    This patch makes Nova:
    a) support Identity v3 params when creating an Ironiccient by
    creating a v3Password auth plugin and a Session;
    b) deprecate auth parameters admin_tenant_name, admin_username
    admin_password and admin_url;
    c) remove support to admin_auth_token auth parameter [1].

    [1] admin_auth_token was deprecated
    (317d9d8f13e8a34af189504ae1258d315154cc82) in favour of admin_username and
    admin_password (which are deprecated now in favour of username and
    password). More info at Keystone release notes (see Deprecation Notes
    and Security Issues):
