To reproduce the problem:
1. With non-English locale set, go to Cloud Intel -> Reports -> Schedules
2. Click 'Add a new schedule' in toolbar button
3. Change the schedule frequency to something else (Daily, Hourly, ...)

The timer_types submitted with the form must not be translated, otherwise the form submission
would fail for non-English locales:

HTTP parse error, malformed request (): #<Puma::HttpParserError:
Invalid HTTP format, parsing fails.>
...

The problem also shows in darga.
