Updated docker images

We have updated the docker images that we internally use. We have made the following changes:

  • awscli image: we upgraded to the V2 of the awscli and Amazon provides an image for that. Therefore we dropped our internal version. We still maintain the image on our end in skyscrapers/aws-cli because we need jq to be installed on that image as well.
  • kops image: this has been replaced by a new kubectl image. This image is based on skyscrapers/aws-cli but with kubectl added on top.
  • cleanup of old unused images: in the scope of having a clean and up to date images we cleaned up the images that we were not using anymore and were therefore not maintained anymore.
