During challenge creation, we'd like to allow a flag to be passed in that determines whether or not the challenge forum should be created during the challenge creation process.

1. By default, create a forum.
2. If the global property to create a forum is turned off, don't create any forums.
3. If the POST request contains ?skipForum=true, don't create the forum.

I believe this is the code we'd need to work with: https://github.com/appirio-tech/direct-app/blob/dev/services/contest_service_facade/src/java/main/com/topcoder/service/facade/contest/ejb/ContestServiceFacadeBean.java#L3663
