[Calendar] Change "available until" date when assignment is dragged in the calendar

[Beth_Young]

It is wonderful to be able to change the due date of an assignment by dragging it in the calendar. However, the "available until" date does not change along with the due date. This sometimes results in assignments being locked before they even open. It would be great if the "available until" date would change at the same time as the due date.

 @woodcock_collee ‌, if that is a request you'd like to support, https://community.canvaslms.com/ideas/12170-relative-due-dates-eg-relative-to-event-start-date is the idea that encompasses that.

Love to use the "mini" shortcut edit page via the calendar view to change due date. I want to see these adds:

• edit due date (current)

• edit "available from" date

• edit "until" date

...and while we're at it, why not a quick "return to home page" button on the calendar view as well.

It has now been almost 4 years. This still hasn't been fixed. 

This is a serious issue. It doesn't make any sense.
