meetings not deleted from Zoom

[lsloan]

When an attendee leaves a queue or meeting, any Zoom meeting created for them remains in the host's list of meetings. They should be removed.

I believe that the current documented workflow is for the host to delete the user before inviting a new one.

9. Once you are done meeting with the attendee (and you have ended the meeting in Zoom, if applicable), return to your queue in Remote Office Hours Queue.1
10. Click the red trash icon next to the attendee you just met with to mark their meeting as completed. This helps other hosts know that you are done meeting with this attendee and are available to meet with other attendees.

I believe we wanted this in the past but this was currently impossible to do otherwise as a callback URL is not available to be set with Zoom to do this automatically. I'm not sure of any other ideas. This was mentioned on the feature on #465 as well to get a duration.
