GitHub uses a library called Licensee to identify a project's license
type. It shows this information in the status bar and via the API if it
can unambiguously identify the license.
This commit modifies a few of SaltStack's docs so that Licensee is able
to recognize the repository's license type. LICENSE has been updated to
contain the full text of the Apache license. COPYING has been removed;
the info regarding external module licensing is now stored at the bottom
of LICENSE.
This commit also adds a "License" section to the README to clarify the
licensing for SaltStack as well as for external modules.
The update to LICENSE and the consolidation of COPYING with LICENSE
allow Licensee to successfully identify the license type of SaltStack as
Apache.
