TOOLSDOC-512: Added OS How To 'Deploy Proj to OSO'

@adietish, @maxandersen : please review and leave comments for any suggestions/required changes.
Not yet, you did not publish your Eclipse project yet: You only prepared your local project to run on OpenShift and created the OpenShift application that will host it. You are required to publish the local project/code to OpenShift via the server adapter. Go to the "Servers" view, choose the server adapter that the wizard created for you and choose "Publish" from its context menu.
