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

+Running VPP
+===========
+
+After building the VPP binaries, you now have several images built.
+These images are useful when you need to run VPP without installing the packages.
+For instance if you want to run VPP with GDB.
+
+Running Without GDB
+_________________________
+
+To run the VPP images that you've built without GDB, run the following commands:
+
+Running the release image:
+
+.. code-block:: console
+
+   # make run-release
+   #
+
+Running the debug image:
+
+.. code-block:: console
+
+   # make run
+   #
+
+Running With GDB
+_________________________
+
+With the following commands you can run VPP and then be dropped into the GDB prompt.
+
+Running the release image:
+
+.. code-block:: console
+
+   # make debug-release
+   (gdb)
+
+Running the debug image:
+
+.. code-block:: console
+
+   # make debug
+   (gdb)
