Add initial concept explanation of self-healing

[sftim]

This is a Feature Request

What would you like to be added
Add a brief page within https://kubernetes.io/docs/concepts/architecture/ that outlines Kubernetes' ability to self-heal, and link to some choice pages that help people learn more.

Why is this needed
https://kubernetes.io#k8s-features-heading says that Kubernetes is self healing but we don't really explain what that means. You can actually set up your cluster to automatically make replacement Pods, replacement storage volumes, replacement nodes etc. Some of that needs extra work. But right now we don't explain the concept.

Comments
Aim to add a minimum viable product - following our style guide etc, and leave room for people to add more detail.

Remember that concise docs are inherently a good thing. People usually don't want more to read.

I would make a new page because we are likely to expand it in the future.
