Inconsistent reference to license for docs

[swinslow]

Hello,

The README.md and LICENSE.docs files are inconsistent about which license applies to the spdystream documentation.

The README.md file says that docs are:
"...licensed under the Creative Commons Attribution 4.0 International License under the terms and conditions set forth in the file "LICENSE.docs". You may obtain a duplicate copy of the same license, titled CC-BY-SA-4.0, at http://creativecommons.org/licenses/by/4.0/."

The bolded items say that the docs license is CC-BY-SA-4.0, but the italicized items say that it is CC-BY-4.0 (which is a different license).

If the intent is for the docs license to be CC-BY-4.0, could the following changes be made?

1. The LICENSE.docs file should likely be replaced with the CC-BY-4.0 license text, available from https://creativecommons.org/licenses/by/4.0/legalcode.txt

2. The bolded reference above to CC-BY-SA-4.0 in README.md should likely be changed to CC-BY-4.0.

Thank you!

For a similar issue in docker/classicswarm, I note that it has now been corrected to refer to CC-BY-SA-4.0 in all cases (see issue, pr).

Is it possible to apply the same changes here, so that the license statement will be consistent?

There are no docs, feel free to open a PR which removes the license.docs and any reference in the Readme. Applying apache 2 to the whole codebase would be consistent with other projects.
