Merge pull request #54463 from saad-ali/volumeAttachmentAPI
Automatic merge from submit-queue. If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>. Introduce new `VolumeAttachment` API Object **What this PR does / why we need it**: Introduce a new `VolumeAttachment` API Object. This object will be used by the CSI volume plugin to enable external attachers (see design [here](https://github.com/kubernetes/community/pull/1258). In the future, existing volume plugins can be refactored to use this object as well. **Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: Part of issue https://github.com/kubernetes/features/issues/178 **Special notes for your reviewer**: None **Release note**: ```release-note NONE ``` Kubernetes-commit: ebe8ea73fd1a961779242dfbb629befa153e96fc
