* Fixed racy panics when using fake watches with ObjectTracker ([#61195](https://github.com/kubernetes/kubernetes/pull/61195), [@grantr](https://github.com/grantr))
* Fixed mounting of UNIX sockets(and other special files) in subpaths ([#61480](https://github.com/kubernetes/kubernetes/pull/61480), [@gnufscied](https://github.com/gnufied))

specified as environment variables. When we convert the OpenStack cloud provider to run in an external process, we can now use the kubernetes Secrets capability to inject the OS_* variables. This way we can specify the cloud configuration as a configmap, and specify secrets for the userid/password information. The configmap is mounted as a file, and the secrets are made available as environment variables. The external controller itself runs as a pod/daemonset. For backward compatibility, we preload...

    * - Don't generate empty record for externalName service.

  // ImagePullSecrets is a list of references to secrets in the same namespace to use for pulling any images
