Fix documentation markdown syntax with lint rule

ref: https://github.com/markdownlint/markdownlint/blob/master/docs/RULES.md

Most of my modified are about following rules:

* MD001 Header levels should only increment by one level at a time
* MD009 Trailing spaces
* MD026 Trailing punctuation in header
* MD027 Multiple spaces after blockquote symbol
* MD031 Fenced code blocks should be surrounded by blank lines

and I change `prereqs/k8s-single-node.md`, `prereqs/k8s-multi-node.md`'s
`Done` to `Next Step`, because with trailling punctuation in header
offend MD026.
