oVPN add Ubuntu endpoint and setup client

I had a need to install something for a client to avoid using RDP port 3389 as Microsoft has a vulnerability and people can exploit it. Now with crypto viruses on the rise, it is never too late to lock things down. Also now that heart bleed is solved – we can get back to this method. This was BEYOND a super explanation that really made my day (it was a long few days) . It is long, but … copy/paste things in and voila – end point complete.
