EKS: Support labels and tags for default worker nodes

[cbek]

User Story

As a Kubestack engineer
I wanna label and tag my EKS default worker nodes
so that I can apply workload specifically.

For Node-Pools it's possible to set labels and tags.

AC

• It's possible to set labels and tags for default worker nodes
• Label and tag options are documented
