**What this PR does / why we need it**: In a 1.8.x master with --leader-elect=false, the garbage collector controller does not work. When deleting a deployment with v1meta.DeletePropagationForeground, the deployment had its deletionTimestamp set and a foreground Deletion finalizer was added, but the deployment, rs and pod were not deleted. This is an issue with how the garbage collector graph_builder behaves when the stopCh=nil. This PR creates a dummy stop channel for the garbage collector controller (and other controllers started by the controller-manager) so that they can work more like they do when when the controller-manager is configured with --leader-elect=true. **Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*: Fixes #57044 **Special notes for your reviewer**: **Release note**: <!-- Write your release note: 1. Enter your extended release note in the below block. If the PR requires additional action from users switching to the new release, include the string "action required". 2. If no release note is required, just write "NONE". --> ```release-note Garbage collection doesn't work when the controller-manager uses --leader-elect=false ``` |

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.
