Looks great to me! Thanks @sblair-metrostar!

@iameskild Made a small change to remove the create_before_destroy setting after more testing. The Nebari node groups are statically named so will conflict with this setting on. Moving to the EKS module will resolve the issue properly, best to wait till then to keep things easy. The ignore part is still fine.
