Allow multiple post-build push to CF steps

[jeanbza]

My app is a java app with several ruby simulators. When I push to review, I can currently push the app itself but not the simulators, as this plugin is limited to one post-build push to CF per project. Thus I have to create an entire new jenkins job just to push these simulators. Would be great if I can specify supply two post-build jobs and perhaps specify a directory.

The issue is 5 years old. @jadekler have you ever won this? :)
