Redis version update

[anrajme]

The latest version of Bitnami/redis is a few revisions ahead of the currently pinned stackstorm-kubernetes chart dependency.

The latest Bitnami upstream version contains several hotfixes. Can we incorporate the latest bitnami/redis chart to StackStorm/stackstorm-k8s?

Yes, that would be very welcome! 👍

Could you open a PR to update the dependencies? We'll be happy to merge that contribution.

I was under the assumption that Redis version bump won't have any direct impact to the stackstorm cluster functionality. However, a few components especially st2-scheduler didn't come online after this change.

Some of the issues like looks to be quite fatal in the version which is currently pinned with stackstorm-kubernetes.

redis/redis#2186

I'm still learning the stackstorm internals, however will see what is the best I can do on this. cheers!

Could you still open a draft PR in this repo?
At least we'll see how the e2e tests would behave.
