Restructured DNS section and expanded each page; added Storage folder and pages

[sfcampbell]

Ugh where to begin...

First I got probably got "writer's loopy" on the DNS section -- if it's too crazy feel free to chop it up as you see fit!

Second I created a "Storage" section where I moved ZFS and added several other blank pages for later.

Lastly I made a total noob mistake pulling before committing a day's worth of changes :vomiting_face: A day in my life haha... Please forgive any quality control edits I may have made before the screw-up and didn't catch before the subsequent commit.

Tomorrow is another day :laughing:
