When running ``behave``, you can now pass a tag like
``--tags=decision.id.not-norm`` or one like
``--tags=decision.id.norm-pres`` to control whether normalization is

- Indicate in comments of Infinite AIPs feature file how to use the
  `-D max_check_aip_stored_attempts=86400` to get behave to wait up to a
  day for an AIP to be created.
- Fix environment.py so that user-supplied attempt counts are coerced to
  ints and user-supplied wait values are coerced to floats.
