Move old blueprints into this repository

Motivation/Why?

We want a single to find all the relevant information about the design of all the systems related to Storj.

What needs to be done?

• Take all the blueprint documents in storj repository that are still applicable (code and logic that remains) and add them to the root of this repository.
• Rename those documents to prefix them with the initial commit date with the format specified in the conventions present in the README.
• Add a frontmatter with the required fields specified in the conventions present in the README.
• Documents that aren't applicable, place them in a folder in the root named archived.

Acceptance criteria

• Add all the blueprint documents in storj repository to this repository.
• Once they are in, delete those documents from the storj repository.

This is a good cleanup task to get done. Let's plan on doing this during sprint 29.

The only part that's missing is to move documents to archived, but, I don't know which ones should be there, so if somebody know, let me know in the review of #12 and I will move them
