Kostiantyn Kalynovskyi 696b287552 Modify executor interface to return channels
Change executors interface to return event channels and allow to
to set event processors. In further development this will allow better
visibility in UI or in command line, also opens the room for concurency.

Also add kubeconfig provider interface that will return kubeconfig.File
object to provide uniform way of accessing kubeconfig
