f9e5dd84ad Graduate image volume sources to beta 
Graduate the feature to beta, by:

- Allowing `subPath`/`subPathExpr` for image volumes
- Modifying the CRI to pass down the (resolved) sub path
- Adding metrics which are outlined in the KEP

7deb49e3a6 Revert "Enforce the Minimum Kernel Version 6.3 for UserNamespacesSupport feature" 
This reverts commit 8597b343fa.

I wrote in the Kubernetes documentation:

	In practice this means you need at least Linux 6.3, as tmpfs started
	supporting idmap mounts in that version. This is usually needed as
	several Kubernetes features use tmpfs (the service account token that is
	mounted by default uses a tmpfs, Secrets use a tmpfs, etc.)

The check is wrong for several reasons:
	* Pods can use userns before 6.3, they will just need to be
	  careful to not use a tmpfs (like a serviceaccount). MOST users
	  will probably need 6.3, but it is possible to use earlier kernel
	  versions. 5.19 probably works fine and with improvements in
          the runtime 5.12 can probably be supported too.
	* Several distros backport changes and the recommended way is
	  usually to try the syscall instead of testing kernel versions.
	  I expect support for simple fs like tmpfs will be backported
	  in several distros, but with this check it can generate confusion.
	* Today a clear error is shown when the pod is created, so it's
	  unlikely a user will not understand why it fails.
	* Returning an error if utilkernel fails to understand what
	  kernel version is running is also too strict (as we are
	  logging a warning even if it is not the expected version)
	* We are switching to enabled by default, which will log a
	  warning on every user that runs on an older than 6.3 kernel,
	  adding noise to the logs.

For there reasons, let's just remove the hardcoded kernel version check.

a2eeec5c5a Revert "Switch hard error to a WARNING for kernel version check" 
This reverts commit fd06dcd604.

The revert is not to make it a hard error again, this revert is needed
to revert cleanly the commit that added this as an error in the first
place.

b6c9c2d6fa 1. When the kubelet constructs the cri mounts for the container which references an image volume source type, It passes the missing mount attributes to the CRI implementation, including readOnly, propagation, and recursiveReadOnly. When the readOnly field of the containerMount is explicitly set to false, the kubelet will take the readOnlyas true to the CRI implementation because the image volume plugin requires the mount to be read-only. 
2. Fix a bug where the pod is unexpectedly running when the `image` volume source type is used and mounted to `/etc/hosts` in the container.
