Phpredis sentinel auth

[McFistyBuns]

Please correct me if I missed something, but it doesn't look like you can pass any password to a sentinel when using Phpredis.

SncRedisBundle/src/Factory/PhpredisClientFactory.php

Lines 124 to 131 in dc5f443

	$address = (new $sentinelClass(
	$dsn->getHost(),
	(int) $dsn->getPort(),
	$connectionTimeout,
	$connectionPersistent,
	5, // retry interval
	$readTimeout,
	))->getMasterAddrByName($masterName);

the Phpredis RedisSentinel class allows for an $auth parameter at the end.

Took me a bit to figure out why my setup was working with predis and not phpredis. I patched in the parameter for myself to pass the password from the parameters config: $options['parameters']['password'] ?? null since my cluster setup uses the same password for both. I could see a more robust path, though, in checking the dsn string for a password first in case the the sentinel and the node passwords are different.

That's correct. PR welcome ;)
