[Inbox] Give users option to automatically archive all conversations based on term

[Justin_Reynolds]

Problem statement:

Some faculty are not proactive about deleting or archiving messages in the Inbox.

Proposed solution:

It would be great if an option existed where users could select to archive messages from the previous term(s) in bulk, rather than having to individually select each message. I could see this being helpful to all users.

User role(s):

admin,instructor,student,ta,designer,observer
