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

-IP Route

-==========

-

-Summary/Usage

---------------

-

-`ip route [add|del] [count <*n*>] <*dst-ip-addr*>/<*width*> [table <*table-id*>] via [next-hop-address[next-hop-interface] [next-hop-table <*value*>] [weight <*value*>] [preference <*value*>] [udp-encap-id <*value*>] [ip4-lookup-in-table <*value*>] [ip6-lookup-in-table <*value*>] [mpls-lookup-in-table <*value*>] [resolve-via-host] [resolve-via-connected] [rx-ip4 <*interface*>] [out-labels <*value value value*>]`

-

-Description

-------------

-

-This command is used to add or delete IPv4 or IPv6 routes. All IP Addresses

-('<*dst-ip-addr*>/<*width*>', '<*next-hop-ip-addr*>' and '<*adj-hop-ip-addr*>') can be IPv4 or IPv6,

-but all must be of the same form in a single command. To display the current set of routes,

-use the commands 'show ip fib' and 'show ip6 fib'.

-

-Example Usage

---------------

-

-Example of how to add a straight forward static route:

-

-.. code-block:: console

-

-    vpp# ip route add 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0

-

-Example of how to delete a straight forward static route:

-

-.. code-block:: console

-

-    vpp# ip route del 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0

-

-Mainly for route add/del performance testing, one can add or delete multiple routes by adding

-'count N' to the previous item:

-

-.. code-block:: console

-

-    vpp# ip route add count 10 7.0.0.0/24 via 6.0.0.1 GigabitEthernet2/0/0

-

-Add multiple routes for the same destination to create equal-cost multipath:

-

-.. code-block:: console

-

-    vpp# ip route add 7.0.0.1/32 via 6.0.0.1 GigabitEthernet2/0/0

-

-    vpp# ip route add 7.0.0.1/32 via 6.0.0.2 GigabitEthernet2/0/0

-

-For unequal-cost multipath, specify the desired weights. This combination of weights

-results in 3/4 of the traffic following the second path, 1/4 following the first path:

-

-.. code-block:: console

-

-    vpp# ip route add 7.0.0.1/32 via 6.0.0.1 GigabitEthernet2/0/0 weight 1

-

-    vpp# ip route add 7.0.0.1/32 via 6.0.0.2 GigabitEthernet2/0/0 weight 3

-

-To add a route to a particular FIB table (VRF), use:

-

-.. code-block:: console

-

-    vpp# ip route add 172.16.24.0/24 table 7 via GigabitEthernet2/0/0

-

-Ping

-=====

-

-Summary/Usage

---------------

-

-ping {<*ip-addr*> | ipv4 <*ip4-addr*> | ipv6 <*ip6-addr*>} [ipv4 <*ip4-addr*> | ipv6 <*ip6-addr*>] [source <*interface*>] [size <*pktsize*>] [interval <*sec*>] [repeat <*cnt*>] [table-id <*id*>] [verbose]

-

-Description

-------------

-

-This command sends an ICMP ECHO_REQUEST to network hosts. The address can be an IPv4 or IPv6

-address (or both at the same time).

-

-Example Usage

---------------

-

-Example of how ping an IPv4 address:

-

-.. code-block:: console

-

-    vpp# ping 172.16.1.2 source GigabitEthernet2/0/0 repeat 2

-

-    64 bytes from 172.16.1.2: icmp_seq=1 ttl=64 time=.1090 ms

-    64 bytes from 172.16.1.2: icmp_seq=2 ttl=64 time=.0914 ms

-

-    Statistics: 2 sent, 2 received, 0% packet loss

-

-    Example of how ping both an IPv4 address and IPv6 address at the same time:

-

-    vpp# ping 172.16.1.2 ipv6 fe80::24a5:f6ff:fe9c:3a36 source GigabitEthernet2/0/0 repeat 2 verbose
