Booker get bookings operations
Relies on !3 (merged) and !4 (merged) (possibly needs a rebase if these are merged)
Adds operations:
- get_room_bookings - bookings between start and end date not booked by essm-sync
- get_event_bookings - bookings in termtime timeframe that were booked by essm-sync
Closes: #14 (closed)
Seem to be unable to add !4 (merged) as MR dependency - GitLab broken
