Add ShareProcessNamespace to PodSpec **What this PR does / why we need it**: This adds an option to the Kubernetes API to configure sharing a process (PID) namespace between the containers in a pod, as described in the [shared pid proposal](https://github.com/verb/community/blob/master/contributors/design-proposals/node/pod-pid-namespace.md). **Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*: WIP #1615 **Special notes for your reviewer**: Questions for API reviewer: - [ ] Is the documentation sufficient to describe the new option? - [x] Does the new field better belong in the security context? - [x] is prepending "alpha" to json/proto fields the right thing to do? **Release note**: ```release-note v1.Pod now has a field to configure whether a single process namespace should be shared between all containers in a pod. This feature is in alpha preview. ```
