Yong Tang 7765e48aaa Remove duplicate keys in labels of `docker info`
This fix tries to address the issue raised in 24392 where
labels with duplicate keys exist in `docker info`, which
contradicts with the specifications in the docs.

The reason for duplicate keys is that labels are stored as
slice of strings in the format of `A=B` (and the input/output).

This fix tries to address this issue by checking conflict
labels when daemon started, and remove duplicate labels (K-V).

The existing `/info` API has not been changed.

An additional integration test has been added to cover the
changes in this fix.

This fix fixes 24392.

docs/README.md

The non-reference docs have been moved!

The documentation for Docker Engine has been merged into the general documentation repo.

See the README for instructions on contributing to and building the documentation.

If you'd like to edit the current published version of the Engine docs, do it in the master branch here: https://github.com/docker/docker.github.io/tree/master/engine

If you need to document the functionality of an upcoming Engine release, use the vnext-engine branch: https://github.com/docker/docker.github.io/tree/vnext-engine/engine

The reference docs have been left in docker/docker (this repo), which remains the place to edit them.

The docs in the general repo are open-source and we appreciate your feedback and pull requests!
