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

-Prefixes
-^^^^^^^^
-
-Some nomenclature used to describe prefixes:
-
-* 1.1.1.1 This is an address since it has no associated mask
-* 1.1.1.0/24 This is a prefix.
-* 1.1.1.1/32 This is a host prefix (the mask length is the size of the address).
-
-Prefix A is more specific than B if its mask length is longer, and less specific if
-the mask is shorter. For example, 1.1.1.0/28 is more specific than 1.1.1.0/24. A
-less specific prefix that overlaps with a more specific is the **covering** prefix.
-For example, 1.1.1.0/24 is the covering prefix for 1.1.1.0/28 and 1.1.1.0/28 is termed
-the **covered** prefix. A covering prefix is therefore always less specific than its
-covered prefixes.
