[server adapter] Allow publishing of wtp-style projects

The openshift server adapter as currently coded simply copies the magic project into a hidden metadata location and executes an rsync. This won't work for any project iwth a custom wtp-style layout and mappings available, including maven projects created via m2ewtp.

This jira targets an initial implementation of a zipped publish of wtp-style projects, both as the magic project or as an added module to be deployed along-side the magic project.
