Support taints/labels on autoscaled node pools

[NiklasRosenstein]

It looks like the autoscaler implementation for Hetzner cloud now supports taints/labels via HCLOUD_CLUSTER_CONFIG which replaces HCLOUD_CLOUD_INIT and HCLOUD_IMAGE!

See https://github.com/kubernetes/autoscaler/blob/master/cluster-autoscaler/cloudprovider/hetzner/README.md

Seems this was added here (kubernetes/autoscaler@e1408ed) and is available in 1.29.0

Would love to see this feature, is there anything where I could help out? ❤️

Sorry for the delay guys. I finally have a week off work this coming week so I am planning a new release that will include this too.

This is now scheduled for 2.0.1. v2.0.0 is going to be released probably next weekend, and 2.0.1 should follow not long after that.

Hi @pashtet04, this change didn't make it into a release yet. I was planning it for 2.0.1 but had to make a couple of releases to fix some more important issues. I will see if I can do it this weekend but I can't promise.
