Create ns.pp

It allows to insert NS records into db zone files
I don't like the commented out thing. Just have two examples if you want to show the array and put the comments at the top of the code block.

But if you do do that, be consistent, because you are missing the dot on the second one, which might surprise someone.

Also, use single quotes in your strings for that to follow the puppet style guide. It is a nice to have, and makes your example code look like official code.
