Guidelines for writing new hacking checks
- Use only for Panko specific tests. OpenStack general tests should be submitted to the common ‘hacking’ module.
 - Pick numbers in the range X3xx. 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 C3xx value.
 - List the new rule in the top level HACKING.rst file
