    Fix filter name inconsistency in stack_list

    As described in the bug report, filter names used in stack_list API are
    not consistent with what users see when creating or retrieving stacks.
    We cannot simply change the exposed filter key names because that will
    break existing users.

    This patch adds a translation logic from STACK_KEYS like 'stack_name' to
    its corresponding db column name, i.e. 'name'. The intent is to provide
    compatibility with existing use cases while enforcing API consistency
    regarding the "properties" a user sees from the API.

    At engine API layer, we also try a simple parsing of the 'status' key,
    which may be of simple form 'FAILED' or complex form 'CREATE_COMPLETE'.
