// address: host:port array
// size: maximum number of idle connections.
// masterName: sentinel master name
// network: tcp or udp
// password: redis-password
// Keys are defined in pairs to allow key rotation, but the common case is to set a single
// authentication key and optionally an encryption key.
//
// The first key in a pair is used for authentication and the second for encryption. The
// encryption key can be set to nil or omitted in the last pair, but the authentication key
// is required in all pairs.
//
// It is recommended to use an authentication key with 32 or 64 bytes. The encryption key,
// if set, must be either 16, 24, or 32 bytes to select AES-128, AES-192, or AES-256 modes.
