I noticed these were out of sync, especially weirdly one mentioning boto and the other mentioning boto3. I figure the list in the README is redundant when the Installation docs section lists the supported libraries, so I've removed it. I also:
* alphabetically sorted the list
* Highlighted the library names as code
* Added both `boto` and `boto3` to the list since there is support for both
* Removed the comment about Tornado's AsyncHTTPClient since that's an implementation detail plus the patch happens on a couple different classes
* Removed the note about `http.client` being part of Python 3, because everyone is Python 3 these days anyway :)
As per [their blog post of the 27th April](https://blog.readthedocs.com/securing-subdomains/) ‘Securing subdomains’:
> Starting today, Read the Docs will start hosting projects from subdomains on the domain readthedocs.io, instead of on readthedocs.org. This change addresses some security concerns around site cookies while hosting user generated data on the same domain as our dashboard.
Test Plan: Manually visited all the links I’ve modified.
When converting objects to body, dicts and sets order can change
resulting in a different but same body. This fixes the issue by
comparing the enclosed data in the body rather than the body itself
while still allowing raw body matching with the raw_body matcher.
