* federation: Adding support for DeleteOptions.OrphanDependents for federated replicasets and deployments. Setting it to false while deleting a federated replicaset or deployment also deletes the corresponding resource from all registered clusters.

## Highlights

* Authorization:
  * **Alpha** RBAC authorization API group
* Federation
  * federation api group is now **beta**
  * Services from all federated clusters are now registered in Cloud DNS (AWS and GCP).
* Stateful Apps:
  * **alpha** PetSets manage stateful apps
  * **alpha** Init containers provide one-time setup for stateful containers
* Updating:

   * difficult to reproduce because they depend on timing. For example:
   *
   * <ul>
   *   <li>When a {@code ListenableFuture} listener is registered to run under {@code
   *       directExecutor}, the listener can execute in any of three possible threads:
   *       <ol>
   *         <li>When a thread attaches a listener to a {@code ListenableFuture} that's already

 * <code>myworkgroup</code> happends to be a workgroup(which is indeed
 * suggested by the name) the <code>list</code> method will return
 * a list of servers that have registered themselves as members of
 * <code>myworkgroup</code>.
 * </td></tr>
 *
 * <tr><td ><code>smb1://</code></td><td>
 * Just as <code>smb1://server/</code> lists shares and

    an `Ingress` creation request to the Federation API Server. The
    Federation control system then creates and maintains a single
    global virtual IP to load balance incoming HTTP(S) traffic across
    some or all the registered clusters, across all regions. Google's
    GCE L7 LoadBalancer is the first supported implementation, and
	is available in this release.
