AB#2074: Add configurable k8s version
Configurable version flow:
* cli config holds/validates k8sVersion
* InitCluster receive a k8sVersion arg
* InitCluster creates CM "k8s-version"
* kubeadm's InitConfiguration receives k8sVersion
* joinservice spec mounts/reads k8s-version CM
* joinservice supplies k8sVersion via JoinTicketResponse
Other changes:
* Remove unused test code (FakeK8SClient)
* move VersionConfig map to /internal/versions
* installk8sComponents is now a function instead of a method
* Run goleak as part of all tests
We are already using goleak in various tests.
This commit adds a TestMain to all remaining tests
and calls goleak.VerifyTestMain in them.
* Add goleak to debugd/deploy package and fix bug.
* Run go mod tidy
* Fix integration tests
* Move goleak invocation for mount integration test
* Ignore leak in state integration tests
