Add support for Kops Cluster on AWS

First of all congratulation for OpsCli !
I think i might be relevent to capture all the user base that build cluster with kops today, even if EKS exist there is still a lot of user that stick with kops because more controle more customisation, less features or options on eks side and so on and so forth...

i would love to see ops support kops cluster that i just discover today searching for something completly different , indeed i was searching for templating solution for my Spinnaker pipeline .
Anyway Kudos for the promising tool.

Cheers
