Absences and discipline: Add dropdown to filter by Grade, House and Counselor

[kevinrobinson]

This is important for SHS housemasters and counselors. For the UX, one suggestion is to add a react-select dropdown only the high school and only for Somerville (see PerDistrict).

• add filter to absences page (Absences: Add filters for house, counselor and grade to fork from current page #2105)
• add filter to discipline page (Add House, Grade, and Counselor Filters to Discipline Dashboard #2186)
• add filter to tardies page
