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

+======================
+Network Stack Features
+======================
+
+This section describes a little about the FD.io network stack and describes some benefits:
+
+* Layer 2 - 4 Network Stack
+
+  * Fast lookup tables for routes, bridge entries
+  * Arbitrary n-tuple classifiers
+  * Control Plane, Traffic Management and Overlays
+
+
+* `Linux <https://en.wikipedia.org/wiki/Linux>`_ and `FreeBSD <https://en.wikipedia.org/wiki/FreeBSD>`_ support
+
+  * Support for standard Operating System Interfaces such as AF_Packet, Tun/Tap & Netmap.
+
+* Network and cryptographic hardware support with `DPDK <https://www.dpdk.org/>`_.
+* Container and Virtualization support
+
+  * Para-virtualized interfaces; Vhost and Virtio
+  * Network Adapters over PCI passthrough
+  * Native container interfaces; MemIF
+
+* Host Stack
+* Universal Data Plane: one code base, for many use cases
+
+  * Discrete appliances; such as `Routers <https://en.wikipedia.org/wiki/Router_(computing)>`_ and `Switches <https://en.wikipedia.org/wiki/Network_switch>`_.
+  * `Cloud Infrastructure and Virtual Network Functions <https://en.wikipedia.org/wiki/Network_function_virtualization>`_
+  * `Cloud Native Infrastructure <https://www.cncf.io/>`_
+  * The same binary package for all use cases.
+
+* Out of the box production quality, with thanks to `CSIT <https://wiki.fd.io/view/CSIT#Start_Here>`_.
