    Improve swift's keystoneauth ACL support

    Below three bug reports talk about one thing.
    Current keystoneauth ACL supports as:

    tenant_name:user_id ok
    tenant_name:user_name no
    tenant_name:* no
    tenant_id:user_id ok
    tenant_id:user_name no
    tenant_id:* no
    *:user_id ok
    *:user_name no
    *:* no

    This patch will make all of above work fine.
    Applying (tenant/user)name could let user put or get their data in a
    more readable way. The tenant_name:* and *:user_name is suitable for
    many usage.

    note: to keep compatibility here add a new keystone.identity just for
    authorize() itself and leave env['keystone.identity'] to other
    middlerwares.
