 A lock is taken through a web interface by the user that wants to access the laser.
 
 When a lock is taken, the Locker will notify a Proxy worker about this address. The Proxy will then perform the UDP proxying. As traffic is proxied, the Proxy will send bump updates to the Locker to extend the lock deadline.
