Allow adding taint for EKS hosted cluster node groups through rancher

[slickwarren]

Is your feature request related to a problem? Please describe.

there is an incoming feature that required adding taints to nodes / node pools in EKS. However, there is not an option for this in the current rancher UI:

Describe the solution you'd like

it would be nice to have a taints section, similar to labels, to taint nodes in a given node group. I'm assuming this can all be done on the front-end

Describe alternatives you've considered

since there's not a create as yaml option in the UI, I've only considered this option through the form. Importing an EKS cluster that was setup through AWS does allow tainting a node group / specific nodes.

Additional context

Need to check with product on the EKS roadmap since this is coming in oddly. @slickwarren did this come through backend work? Do you have linked tickets there?
