Update the docs/development directory

MS6 requires to have the docs directory structure ready and a preliminary
versio of the documents inside it.

- Moved requirements file to the requirements folder
- Removed the NSH workaround info as we don't need it anymore
- Added some new requirements

-OVS NSH patch workaround
-++++++++++++++++++++++++
-
-When using NSH with VXLAN tunnels, it is important that the VXLAN tunnel is
-terminated in the SF VM. This allows the SF to see the NSH header, allowing
-it to decrement the NSI and also to use the NSH metadata. When using VXLAN with
-OpenStack, the tunnels are not terminated in the VM, but in the "br-int" OVS
-bridge. There is work ongoing in the upstream OVS community to implemement NSH
-encapsulation. To get around the way OpenStack handles VXLAN tunnels, the OVS
-work will also include the ability to encapsulate/decapsulate VXLAN tunnels from
-OpenFlow rules, instead of relying on the Vtep ports. The ongoing upstream OVS
-work will not be finished by the time OPNFV Danube is released, so
-a work-around has been created. This work-around will use a private branch of
-OVS that has a preliminary version of NSH implemented.

-Requirements
-------------
-
-This section defines requirements for the initial OPNFV SFC implementation,
-including those requirements driving upstream project enhancements.
-
-Minimal Viable Requirement
-++++++++++++++++++++++++++
-
-Deploy a complete SFC solution by integrating OpenDaylight SFC with OpenStack
-in an OPNFV environment.
-
-Detailed Requirements
-+++++++++++++++++++++
-
-These are the Danube specific requirements:
-
-1 The supported Service Chaining encapsulation will be NSH VXLAN-GPE.
-
-2 The version of OVS used must support NSH.
-
-3 The SF VM life cycle will be managed by the Tacker VNF Manager.
-
-4 The supported classifier is OpenDaylight NetVirt.
-
-5 ODL will be the OpenStack Neutron backend and will handle all networking
-  on the compute nodes.
-
-Long Term Requirements
-++++++++++++++++++++++
-
-These requirements are out of the scope of the Danube release.
-
-1 Dynamic movement of SFs across multiple Compute nodes.
-
-2 Load Balancing across multiple SFs
-
