Added RecreateNodeAnnotationKey const (#16)

* Added RecreateNodeAnnotationKey const

And improved documentation for RestartedAtAnnotationKey

* Improved documentation

* Added one more case

* improved comments.

* removed space

* not --> none

* switched order

* more line shuffling

* added requirement of CM

* Addressed comments (annot will be placed on pod)

* Value from annot is free to use. Added Status.ScaleDownNodeIndex field

And improved some comments

* added non-empty
