docs: better docs, mv doxygen to sphinx
This patch refactors the VPP sphinx docs
in order to make it easier to consume
for external readers as well as VPP developers.
It also makes sphinx the single source
of documentation, which simplifies maintenance
and operation.
Most important updates are:
- reformat the existing documentation as rst
- split RELEASE.md and move it into separate rst files
- remove section 'events'
- remove section 'archive'
- remove section 'related projects'
- remove section 'feature by release'
- remove section 'Various links'
- make (Configuration reference, CLI docs,
developer docs) top level items in the list
- move 'Use Cases' as part of 'About VPP'
- move 'Troubleshooting' as part of 'Getting Started'
- move test framework docs into 'Developer Documentation'
- add a 'Contributing' section for gerrit,
docs and other contributer related infos
- deprecate doxygen and test-docs targets
- redirect the "make doxygen" target to "make docs"
Type: refactor
