Ability for a Confluence Questions topics to be linked to HipChat rooms and send HipChat notifications

You can currently link questions asked in a Space to a HipChat room (as of CQ 2.1), this issue is to track the ability to link a topic to a room.

If you are going to comment on this ticket we'd love to hear from you on why you want this to get a better understanding:

• Is it because the topic does not relate to a space?
• Is it because you want a topic to link to multiple sapces?
• .... something else?

Any examples would be great!
