/**
 * Updates the configuration of a MUC service.
 *
 * This is more involved than it may seem.
 *
 * If the subdomain is changed, we need to shut down the old service and start up the new one, registering
 * the new subdomain and cleaning up the old one.
 *
 * Properties are tied to the ID, which will not change.
 *
 * @param serviceID The ID of the service to be updated.
 * @param subdomain New subdomain to assign to the service.
 * @param description New description to assign to the service.
 * @throws NotFoundException if service was not found.
