Allow a BOF organizer to schedule it

Problem/Motivation

Currently, in-person events sometimes allow BOF organizers to pick the time slot and room. Ideally the Event Platform would provide this capability as well.

Proposed resolution

This could be as simple as allowing the user to see and fill out the related fields. Additional validation would be needed to check for conflicts.

Alternatively, there could be some kind of interface that allows the organizer to choose a time and room combination from the available options.
