Implement facility booking for a period of time

[itachi1706]

A service that allows a user to book a facility for a period by specifying the facility name and the start and end times of the booking. On successful booking, a unique confirmation ID is returned to the client and the availability of the facility should be updated at the server. In case of incorrect user input (e.g., non-existing facility name or the facility is completely or partially unavailable during the requested period due to existing bookings), a proper error message should be returned.
