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

-### Setting Up a Custom Management Network on Multi-Homed Nodes
-
-If the interface you use for Kubernetes management traffic (for example, the
-IP address used for `kubeadm join`) is not the one that contains the default
-route out of the host, then you need to specify the management node IP address in
-the Kubelet config file. Add the following line to:
-(`/etc/systemd/system/kubelet.service.d/10-kubeadm.conf`):
-```
-Environment="KUBELET_EXTRA_ARGS=--fail-swap-on=false --node-ip=<node-management-ip-address>"
-```
-#### Example
-Consider a 2 node deployment where each node is connected to 2 networks -
-`10.0.2.0/24` and `192.168.56.0/24`, and the default route on each node points
-to the interface connected to the `10.0.2.0/24` subnet. We want to use subnet
-`192.168.56.0/24` for Kubernetes management traffic. Assume the addresses of
-nodes connected to `192.168.56.0/24` are `192.168.56.105` and `192.168.56.106`.
-
-On the `192.168.56.105` node you add the following line to `10-kubeadm.conf`:
-```
-Environment="KUBELET_EXTRA_ARGS=--fail-swap-on=false --node-ip=192.168.56.105"
-```
-On the `192.168.56.106` node you add the following line to `10-kubeadm.conf`:
-```
-Environment="KUBELET_EXTRA_ARGS=--fail-swap-on=false --node-ip=192.168.56.106"
-```
