Object Cluster will be a entry point to intractions with kubernetes It will provide: - kubectl abstraction which will emulate kubectl apply and other commands (in the future) - kubernets client-go kubernetes interface which has all operations, including CRUD to kubernetes apps, core, extentions, etc... objects Change-Id: Ie2961f68a160e720c264c622c1124f283bded161
