Support TLS for Predis

I completely agree with @eelkeblok, if the issue already provide a MR is not needed/good to add patch and even worse without an interdiff.

The only difference I see between last patch and the MR is the following, which should not be responsibility of this issue.

+++ b/src/ClientFactory.php
@@ -27,6 +32,11 @@ class ClientFactory {
+  /**
+   * Redis default scheme: will not authenticate.
+   */
+  const REDIS_DEFAULT_SCHEME = 'tcp';

That being said, I tested the patch from the MR and it is working fine, so I just re-rolled, moved the new parameter to the end of some config arrays and fixed some CS.

The patch from #37 fixed the issue in Drupal Version 9.5.10 and redis 1.7.0.
Can this be merged into the next stable release?
Thank you

Needs a rebase.
