Comply with the standards of the Bazel federation (#182)

* Comply with the standards of the Bazel federation

This commit allows bazel_skylib to be a member of the Bazel federation, since it adds the required bzl files related to setup and dependencies.
Moreover, it also changes the WORKSPACE to fetch all dependencies through the federation.

* Add copyright and docstring to bzl files
