Guidelines for writing new hacking checks

- Use only for Heat specific tests. OpenStack general tests
  should be submitted to the common 'hacking' module.
- Pick numbers in the range H3xx. Find the current test with
  the highest allocated number and then pick the next value.
- Keep the test method code in the source file ordered based
  on the HE3xx value.
- List the new rule in the top level HACKING.rst file
- Add test cases for each new rule to heat/tests/test_hacking.py
