Automatic merge from submit-queue kubectl: Use v1.5-compatible ownership logic when listing dependents. **What this PR does / why we need it**: This restores compatibility between kubectl 1.6 and clusters running Kubernetes 1.5.x. It introduces transitional ownership logic in which the client considers ControllerRef when it exists, but does not require it to exist. If we were to ignore ControllerRef altogether (pre-1.6 client behavior), we would introduce a new failure mode in v1.6 because controllers that used to get stuck due to selector overlap will now make progress. For example, that means when reaping ReplicaSets of an overlapping Deployment, we would risk deleting ReplicaSets belonging to a different Deployment that we aren't about to delete. This transitional logic avoids such surprises in 1.6 clusters, and does no worse than kubectl 1.5 did in 1.5 clusters. To prevent this when kubectl 1.5 is used against 1.6 clusters, we can cherrypick this change. **Which issue this PR fixes**: Fixes #43159 **Special notes for your reviewer**: **Release note**: ```release-note ``` |

Kubernetes
Kubernetes is an open source system for managing containerized applications across multiple hosts, providing basic mechanisms for deployment, maintenance, and scaling of applications.
Kubernetes builds upon a decade and a half of experience at Google running production workloads at scale using a system called Borg, combined with best-of-breed ideas and practices from the community.
Kubernetes is hosted by the Cloud Native Computing Foundation (CNCF). If you are a company that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details about who's involved and how Kubernetes plays a role, read the CNCF announcement.
To start using Kubernetes
See our documentation on kubernetes.io.
Try our interactive tutorial.
Take a free course on Scalable Microservices with Kubernetes.
To start developing Kubernetes
The community repository hosts all information about building Kubernetes from source, how to contribute code and documentation, who to contact about what, etc.
If you want to build Kubernetes right away there are two options:
You have a working Go environment.
$ go get -d k8s.io/kubernetes
$ cd $GOPATH/src/k8s.io/kubernetes
$ make
You have a working Docker environment.
$ git clone https://github.com/kubernetes/kubernetes
$ cd kubernetes
$ make quick-release
If you are less impatient, head over to the developer's documentation.
Support
If you need support, start with the troubleshooting guide and work your way through the process that we've outlined.
That said, if you have questions, reach out to us one way or another.
