Add docs and middleware for dynoid

[kennyp]

Rationale

Dyno identity should be easy to adopt.

Changes

• Add docs and refactor dynoid and dynoid/dynoidtest.
• Add http middleware to dynoid/middleware to simplify incorporating dynoid.

This looks really good.

I do have one reservation about putting the middleware under the hmiddleware package even though it seems like the best fit. This module has quite a few dependencies and I think it would be great if we could eventually break it up a bit.

The dyno ID bits will need to remain together so may consider moving it to dynoid/dynoidmiddleware instead? That also prevents two packages that are named identically for import purposes.

I think a readme.md with some basics on how to use this package would be really helpful. That said, the inline comments definitely help, as does having the tests nearby to use as an example.

A few suggestions but still looks good.

Thanks for the suggestions @tt. I've incorporated your feedback.

I agree with you @mjrossi, but I figured I would hold off on that until we some devcenter articles and a blog post to link to.
