Fixed NOTE bugs, unnecessary [*] mark, lots of remnant code[...]

I found some issues where !!! Note was used instead of
```
**Note: **
```

There was also an unnecessary ```[*]``` mark in authors-testing. I assume a list item used to be here, but since this is a single step item and the ```[*]``` was not being rendered, I opted to remove it entirely.

The How To - Private Cloud had a lot of old code that looked like it was a remnant from an old doc header or table of contents, which simply isn't being used and took up a lot of page space.
