This adds a recipe to build a package of graylog-server with the enterprise plugins bundled in.

@bernd I don't want to duplicate all these files between the graylog-server directory and the graylog-enterprise directory. What would you think if I replaced most of the files in the graylog-enterprise directory with symlinks? That way, they could be updated in one place.

@juju2112 Good point! We can do the following to reuse the files from the server. That way we don't have to deal with symlinks.

@juju2112 Forgot to mention it explicitly: with that diff we can completely remove the files/ folder in the new package recipe.
