* [alpha] Mount namespace propagation

  * The `VolumeMount.Propagation` field for `VolumeMount` in pod containers is now available.

  * You can now set `VolumeMount.Propagation` to `Bidirectional` to enable a particular mount for a container to propagate itself to the host or other containers.

- Added request header UID propagation, behind an alpha `RemoteRequestHeaderUID` feature gate. ([#129081](https://github.com/kubernetes/kubernetes/pull/129081), [@stalz](https://github.com/stlaz)) [SIG API SIG API Machinery, cluster lifecycle, testing]
