title: set a price cap for spot instances with EKS
body: <p>I would like to use spot instances in my cluster. I was trying to create a node group with a spot priced launch template when I discovered it's not possible to specify instance market options like maximum price.</p>

  <p>This seems like a pretty major limitation seeing as spot instances can spike up in price to orders of magnitude more than on-demand.</p>

  <p>Is there really no way around this? Is no one using spot instances in EKS?</p>
