Remove various tests and utilities related to testing kubernetes support Also removing the Kubernetes and DefaultStackOrchestrator from CreateOptions and UpdateOptions, instead updating the flags to not be bound to a variable. This might break some consumers of those options, but given that they've become non-functional, that's probably ok (otherwise they may ignore the deprecation warning and end up with non-functional code).
