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

@adietish, @maxandersen : please review and leave comments for any suggestions/required changes.
this is not valid any more. The wizard only prepares the local project, it will not commit and push the changes back to OpenShift: https://issues.jboss.org/browse/JBIDE-17984
The user is required to explicitly publish the local changes to OpenShift via the server adapter.
