[Course Settings] Different default times with minutes for to-do, available, due, and lock times

Problem statement:

The course settings include a single default time option with a list of any hour on the hour, and one option set already to 11:59pm. Teachers have many reasons for setting different times, including the start and end of synchronous meetings, and a desire to have a time without a busy server. The times desired tend to vary by the type of time: to-do, available, due, and lock. The single default time does not cover the many types of times now used, and the lack of options for minutes does not match enough course requirements.

Proposed solution:

In each course, add types of times to the default time to include to-do, available, due, and lock times, and then for each type, allow the entire standard clock of times. This will allow teachers to more quickly select the times they use the most when creating new content.
