Reference Issue: https://github.com/kubernetes/website/issues/41084
1. Exec probe's implementation involves the Kubelet making a gRPC call to the
underlying CRI which inturn involves in the creation of multiple processes that
require a good amount of cpu usage whenever the probe is executed.
2. Whereas the other probes namely `http/gRPC/tcp` involves the Kubelet alone making
a call to the container.
3. There might be a significant amount of cpu overhead in the cases of
higher pod densities, lower periodic intervals when the exec probe is configured.
4. Hence, it would be a good idea to alert the user to opt for the other available probes
in case of the above mentioned scenarios.

containerd 1.7 was just released with user namespaces support. Let's
mention which kubernetes versions should work with container 1.7.
While we are there, let's clarify the CRI-O version and not duplicate
the requirements in the concept and task pages and just add a link
