Our translation policy
(https://wiki.openstack.org/wiki/LoggingStandards#Log_Translation) calls
for not translating debug level logs. This is to help prioritize log
translation. Furthermore translation has a performance overhead, even if
the log isn't used (since nova doesn't support lazy translation yet).
Remove unnecessary debug level log translation in the scheduler to
comply with our translation policy. This has the added benefit of making
the scheduler slightly faster too.
Add a local hacking rule to enforce this.
