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

-# Debug CLI    {{'{#'}}clicmd}
-
-The VPP network stack comes equipped with a set of commands that are useful
-for debugging.
-
-The easiest way to access the CLI (with proper permissions) is to use the
-vppctl command:
-
-```
-sudo vppctl <cli-command>
-```
-
-The CLI parser matches static keyword strings, eventually invoking an action
-function. Unambiguous partial keyword matching always occurs. The action
-functions consume input until satisfied or until they fail. This model makes
-for easy coding, but does not guarantee useful "help" output. It's up to the
-CLI command writer to add useful help strings.
-
-You can find the source code of CLI commands by searching for instances of the
-@c VLIB_CLI_COMMAND macro in the code source files.
-
-Please help maintain and improve this document to make and keep these commands
-clear and useful!
-
-@todo Document where to modify this CLI intro text.
-
-
-## Debug and Telnet CLI
-
-The debug CLI is enabled with the unix interactive parameter or startup
-configuration option. This causes VPP to start without daemonizing and
-presents a command line interface on the terminal where it is run.
-
-The Telnet CLI is enabled with the `cli-listen localhost:5002` option which
-will cause VPP to listen for TCP connections on the localhost address port
-@c 5002. A Telnet client can then connect to this port (for example, `telnet
-localhost 5002`) and will receive a command line prompt.
-
-This configuration will enable both mechanisms:
-
-```
-unix {
-  interactive
-  cli-listen localhost:5002
-}
-```
-
-The debug CLI can operate in line mode, which may be useful when running
-inside an IDE like Emacs. This is enabled with the option
-`unix cli-line-mode`. Several other options exist that alter how this
-CLI works, see the @ref syscfg section for details.
-
-The CLI starts with a banner graphic (which can be disabled) and a prompt. The
-prompt will typically read `vpp` for a release version of VPP and `DBGvpp#`
-for a development version with debugging enabled, for example:
-
-        _______    _        _   _____  ___ 
-     __/ __/ _ \  (_)__    | | / / _ \/ _ \
-     _/ _// // / / / _ \   | |/ / ___/ ___/
-     /_/ /____(_)_/\___/   |___/_/  /_/    
-    
-    vpp# 
-
-versus:
-
-        _______    _        _   _____  ___ 
-     __/ __/ _ \  (_)__    | | / / _ \/ _ \
-     _/ _// // / / / _ \   | |/ / ___/ ___/
-     /_/ /____(_)_/\___/   |___/_/  /_/    
-    
-    DBGvpp# 
-
-This prompt can be configured with the `unix cli-prompt` setting and the
-banner is disabled with `unix cli-no-banner`.
-
-## CLI features
-
-The CLI has several editing features that make it easy to use.
-
-- Cursor keys left/right will move the cursor within a command line;
-  typing will insert at the cursor; erase will erase at the cursor.
-
-- Ctrl-left/right will search for the start of the next word to
-  the left or right.
-- Home/end will jump the cursor to the start and end of the line.
-- Cursor keys up/down and ^P/^N iterate through the command history
-  buffer. Lines from the history buffer may be edited. New commands
-  are added to the end of the buffer when executed; though
-  duplicates of the previous command are not added.
-- ^U erases the line contents from the left of the cursor to the
-  start.
-- ^K erases the contents from the cursor to the end.
-- ^S/^R will search the command history forwards or in reverse for
-  a command; start typing for matches to auto complete.
-- ^L will clear the screen (if supported by the terminal) and repaint
-  the prompt and any current line. The cursor position is also
-  retained.
-- The CLI can be closed with the quit command. Alternatively, ^D on
-  an empty input line will also close the session. Closing the debug
-  session will also shutdown VPP.
-
-Output that exceeds the length of a terminal page will be buffered, up to a
-limit.
-
-- Space or page-down displays the next page.
-- Enter or down-arrow displays the next line.
-- Page-up goes back a page.
-- Up-arrow goes up a line.
-- Home/end jump to the start/end of the buffered output.
-- The key q quits the pager. Space and enter will also quit the
-  pager if the end of the buffer has been reached.

-# Startup Configuration    {{'{#'}}syscfg}
-
-The VPP network stack comes with several configuration options that can be
-provided either on the command line or in a configuration file.
-
-Specific applications built on the stack have been known to require a dozen
-arguments, depending on requirements. This section describes commonly-used
-options and parameters.
-
-You can find command-line argument parsers in the source code by searching for
-instances of the `VLIB_CONFIG_FUNCTION` macro. The invocation
-`VLIB_CONFIG_FUNCTION(foo_config, "foo")` will cause the function
-`foo_config` to receive all the options and values supplied in a parameter
-block named "`foo`", for example: `foo { arg1 arg2 arg3 ... }`.
-
-@todo Tell the nice people where this document lives so that the might
-help improve it!
-
-## Command-line arguments
-
-Parameters are grouped by a section name. When providing more than one
-parameter to a section all parameters for that section must be wrapped in
-curly braces.
-
-```
-/usr/bin/vpp unix { interactive cli-listen 127.0.0.1:5002 }
-```
-
-Which will produce output similar to this:
-
-    <startup diagnostic messages>
-        _______    _        _   _____  ___ 
-     __/ __/ _ \  (_)__    | | / / _ \/ _ \
-     _/ _// // / / / _ \   | |/ / ___/ ___/
-     /_/ /____(_)_/\___/   |___/_/  /_/    
-    
-    vpp# <start-typing>
-
-When providing only one such parameter the braces are optional. For example,
-the following command argument, `unix interactive` does not have braces:
-
-```
-/usr/bin/vpp unix interactive
-```
-
-The command line can be presented as a single string or as several; anything
-given on the command line is concatenated with spaces into a single string
-before parsing.
-
-VPP applications must be able to locate their own executable images. The
-simplest way to ensure this will work is to invoke a VPP application by giving
-its absolute path; for example: `/usr/bin/vpp <options>`. At startup, VPP
-applications parse through their own ELF-sections (primarily) to make lists
-of init, configuration, and exit handlers.
-
-When developing with VPP, in _gdb_ it's often sufficient to start an application
-like this at the `(gdb)` prompt:
-
-```
-run unix interactive
-```
-
-## Configuration file
-
-It is also possible to supply parameters in a startup configuration file the
-path of which is provided to the VPP application on its command line.
-
-The format of the configuration file is a simple text file with the same
-content as the command line but with the benefit of being able to use newlines
-to make the content easier to read. For example:
-
-```
-unix {
-  nodaemon
-  log /var/log/vpp/vpp.log
-  full-coredump
-  cli-listen localhost:5002
-}
-api-trace {
-  on
-}
-dpdk {
-  dev 0000:03:00.0
-}
-```
-
-VPP is then instructed to load this file with the `-c` option:
-
-```
-/usr/bin/vpp -c /etc/vpp/startup.conf
-```
