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

-VPP in Azure
-___________________
-
-
-
-
-Before starting, a few notes:
-
-* in our configuration we use only DPDK 18.02, since with the newer versions, such as DPDK 18.05, we obtained several problems during VPP installation (mostly related with MLX4 PMD Drivers). 
-
-* Some of the commands are taken from `Azure’s DPDK page <https://docs.microsoft.com/en-us/azure/virtual-network/setup-dpdk>`_.
-
-To bring DPDK inside Azure, we perform the following procedure:
-
-Firstly, we install the DPDK dependencies:
-
-.. code-block:: console
-
- $ sudo add-apt-repository ppa:canonical-server/dpdk-azure –y
- $ sudo apt-get update
- $ sudo apt-get install -y librdmacm-dev librdmacm1 build-essential libnuma-dev libmnl-dev
-
-Then, we download DPDK 18.02:
-
-.. code-block:: console
-
- $ sudo wget https://fast.dpdk.org/rel/dpdk-18.02.2.tar.xz
- $ tar -xvf dpdk-18.02.2.tar.xz
-
-Finally, we build DPDK, modifying first its configuration files in order to make VPP compatible with MLX4 drivers:
-
-Inside config/common_base, modify:
-
-.. code-block:: console
-
-  CONFIG_RTE_BUILD_SHARED_LIB=n
-  CONFIG_RTE_LIBRTE_MLX4_PMD=y
-  CONFIG_RTE_LIBRTE_MLX4_DLOPEN_DEPS=y
-  CONFIG_RTE_LIBRTE_TAP_PMD=y
-  CONFIG_RTE_LIBRTE_FAILSAFE_PMD=y
-
-and then:
-
-.. code-block:: console
-
- $ make config T=x86_64-native-linuxapp-gcc
- $ sed -ri 's,(MLX._PMD=)n,\1y,' build/.config
- $ make
-
-Finally we build DPDK:
-
-.. code-block:: console
-
- $ make install T=x86_64-native-linuxapp-gcc DESTDIR=/home/ciscotest/test EXTRA_CFLAGS='-fPIC -pie'
-
-And we reboot the instance:
-
-.. code-block:: console
-
- $ reboot instance
-
-After the reboot, we type these commands:
-
-.. code-block:: console
-
- $ echo 1024 | sudo tee /sys/devices/system/node/node*/hugepages/hugepages-2048kB/nr_hugepages
- $ mkdir /mnt/huge
- $ sudo mount -t hugetlbfs nodev /mnt/huge
- $ grep Huge /proc/meminfo
- $ modprobe -a ib_uverbs
- $ cd x86_64-native-linuxapp-gcc/
- $ ls
- $ cd lib/
- $ ls
- $ sudo cp librte_pmd_mlx4_glue.so.18.02.0 /usr/lib
-
-**Now we focus on VPP installation:**
-
-In our configuration we use VPP 18.07.
-
-We perform this procedure in order to install VPP 18.07 with an external DPDK configuration inside Azure.
-
-Firstly, we download VPP
-
-.. code-block:: console
-
- $ git clone https://gerrit.fd.io/r/vpp
- $ git checkout v18.07
-
-Then, we build VPP, using the external DPDK configuration we previously made:
-
-We modify the path inside the vpp.mk file:
-
-.. code-block:: console
-
- $ build-data/platforms/vpp.mk
- $ vpp_uses_external_dpdk = yes
- $ vpp_dpdk_inc_dir = <PATH_TO_DESTDIR_NAME_FROM_ABOVE>/include/dpdk/
- $ vpp_dpdk_lib_dir =<PATH_TO_DESTDIR_NAME_FROM_ABOVE>/lib
-
-<PATH_TO_DESTDIR_NAME_FROM_ABOVE> is whatever the path used when compiling DPDK above. These paths have to be absolute path in order for it to work.
-
-we modify build-data/platforms/vpp.mk to use
-
-.. code-block:: console
-
- vpp_uses_dpdk_mlx4_pmd = yes
-
-.. code-block:: console
-
- $ make build
- $ cd build-root/
- $ make V=0 PLATFORM=vpp TAG=vpp install-deb
- $ sudo dpkg -i *.deb
-
-Finally, we modify the startup.conf file:
-
-.. code-block:: console
-
- $ cd /etc/vpp
- $ sudo nano startup.conf
-
-Inside the DPDK block, the following commands:
-
-.. code-block:: console
-
-
- ## Whitelist specific interface by specifying PCI address
- dev 000X:00:0X.0
- dev 000X:00:0X.0
- 
- # Running failsafe
- vdev net_vdev_netvsc0,iface=eth1
- vdev net_vdev_netvsc1,iface=eth2
-
-*Please refer to Azure DPDK document to pick the right iface to use for failsafe vdev.*
-
-
-and finally:
-
-.. code-block:: console
-
- $ sudo service vpp stop
- $ sudo service vpp start
- $ sudo service vpp status
- $ sudo vppctl
-
-Now VPP will work inside Azure!
