    Add metrics notifier to Pecan

    This adds the standard 'object.(create|update|delete).(start|end)'
    notifications to the Pecan notification hook and adds unit tests
    to exercise them.

    This patch also corrects the on_error handler for untranslated
    exceptions which was incorrectly raising the exception rather than
    returning it. This was resulting in the other hooks not getting
    the correct status code on an untranslated exception.
