As suggested by @matas-valuzis, this will enable TLS support for Redis transport.

Configure it with the following DSN

```
redis://127.0.0.1?tls=1
```

The implementation just prefix the host with `tls://` as described here: https://github.com/phpredis/phpredis#connect-open

It is already possible to use TLS with the Redis transport, but there are not support in the DSN until now.
