/**
 * Enables Laravel's Redis database driver to accept configuration options for
 * Redis Sentinel connections independently. Replaces Laravel's RedisManager
 * for Redis Sentinel connections.
 *
 * By default, Laravel's Redis service permits a single set of configuration
 * options for all of the Redis connections passed to the Predis client. This
 * prevents us from declaring separate parameters for individual Redis services
 * managed by Sentinel. For example, we may wish to connect to a separate Redis
 * Sentinel service cluster set, or use a separate Redis database, for caching
 * queues, and sessions. This wrapper class enables us to declare parameters
 * for each connection in the "redis-sentinel" block of the database
 * configuration which it will use to configure individual clients.
 *
 * Laravel changed the public interface of the RedisManager class in version
 * 5.4.20. Because this package extends the functionality of that class, the
 * implementation needed to change to match the modified interface. To avoid
 * frivolous package versioning and simplify installation and upgrade through
 * composer, this class handles any small differences between minor Laravel
 * versions by wrapping implementations of RedisSentinelManager for each
 * diverging Laravel version.
