[spp] [PATCH 01/11] docs: change structure of overview section

[ogawa.yasufumi@lab.ntt.co.jp]

From: Yasufumi Ogawa <ogawa.yasufumi@lab.ntt.co.jp>

This patche is to divide `overview.rst` to sub sections for adding more
contents to this section. All of design sections, for instance spp-ctl,
are moved to under this overview section in next patches.

-    SPP overview
-
-With SPP, user is able to configure network easily and dynamically
-via simple patch panel like interface.
-
-The goal of SPP is to easily interconnect NFV applications via high
-thoughput network interfaces provided by DPDK and change configurations
-of resources dynamically to applications to build pipelines.
-
-
-Design
-------
-
-SPP is composed of several DPDK processes and controller processes [1].
-
-In terms of DPDK processes, SPP is derived from DPDK's multi-process sample
-application and it consists of a primary process and multiple secondary
-processes.
-SPP primary process is responsible for resource management, for example, ports,
-mbufs or shared memory. On the other hand, secondary processes are working for
-tasks.
-
-SPP is controlled from python based management framework. It consists of
-front-end CLI and back-end server process.
-SPP's front-end CLI provides a patch panel like interface for users.
-This CLI process parses user input and sends request to the back-end via REST
-APIs. It means that the back-end server process accepts requests from other
-than CLI. It enables developers to implement control interface such as GUI, or
-plugin for other framework.
-`networking-spp
-<https://github.com/openstack/networking-spp>`_
-is a Neutron ML2 plugin for using SPP with OpenStack.
-By using networking-spp and doing some of extra tunings for optimization, you
-can deploy high-performance NFV services on OpenStack [2].
