Kengo Takahara 0cdbbf669d Remove log translations
Log messages are no longer being translated. This removes all use of
the _LC, _LE, _LI and _LW translation markers to simplify logging and to
avoid confusion with new contributions.

Guidelines for writing new hacking checks
- Use only for masakarimonitors specific tests. OpenStack general tests
should be submitted to the common 'hacking' module.
- Pick numbers in the range M3xx. 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 M3xx value.
- List the new rule in the top level HACKING.rst file
- Add test cases for each new rule to masakarimonitors/tests/unit/
