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 Change-Id: Icca89c738b1eb1865adff510ca2850c592c7a14a Signed-off-by: Manuel Buil <mbuil@suse.com>

-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.
