Discussion Boards - Create an option to "Expand Threads" by default

Problem statement:

The new discussion board UI automatically hides replies to posts on the discussion boards. There is an option to "Expand Threads" which shows all replies, however we are hearing from faculty that they and students aren't interacting with replies because they aren't easily seen.

Proposed solution:

A solution would be to make a discussion or course setting to either expand or collapse threads by default, instead of always collapsing threads. This would allow users that prefer collapsed threads in their course to still have the existing option, but faculty that would like to have replies more obvious to students would have that option as well.

User role(s):

admin,instructor,ta,designer
