/**
 * Message sender implementing {@link Sender} to use a redis database with its build-in publish/subscribe function as
 * message broker. Following platform properties are needed (default value in brackets):
 * <ul>
 * <li>redisMessagingHost (localhost): Host of the redis server</li>
 * <li>redisMessagingPort (6379): Port of the redis server</li>
 * <li>redisMessagingPassword (): Password of the redis server</li>
 * <li>redisMessagingTimeout (): Timeout is optional. If not defined, Redis default is used</li>
 * <li>redisMessagingChannel (appng-messaging): Channel where all cluster nodes should publish and subscribe. Be aware
 * that this name must be the same for all nodes within a cluster and must be different among different clusters using
 * the same Redis server</li>
 * </ul>
