Fail gracefully when Redis not available

The idea is great, but the implementation should be doing it such that we don't have duplicate lines of code just next to each other. The existing fallback should be used if the Redis approach fails.

Please update the MR so that it works against the 1.2.x branch. Development always works in the latest branch and if it's a bug fix, it will then be back ported to previous supported versions.

I'm not using D11 yet :( it'd be great if 1.2 would have support for D10

Doesn't matter. As I mentioned before, we can back port to older versions. But development always works on the latest branch.

It's better, just left 1 suggestion on how this could be easier to read.

Merged and back ported. Thank you @pcambra for your contribution.

Awesome, thanks!
