    Refactor: remove token formatters dep on 'token_data' on create()

    The calling module already has to understand how token_data is composed,
    so there's no reason for the token formatters create() method to work
    with such complex data. This patch ensures that token formatters only
    see primitive strings (of datetimes, audit IDs, and trust IDs) when
    creating tokens, which they're free to encode however they wish.

    The subsequent patch removes the same dependency in validate().

    As part of this refactor, bug 1428829 is also addressed by simplifying
    how audit_ids are handled (they're not mutated any more than strictly
    necessary).
