Non-commiters are unable to checkout submodules.

Most users will checking this project out and following the wiki will immediately encounter:

storm-contrib$ git submodule update Permission denied (publickey). fatal: The remote end hung up unexpectedly Unable to fetch in submodule path 'storm-backport'`

Please provide a useful storm-contrib project to those people who are not also commiters for all of the sub-projects.

Two fixes available, both linked above. First retains the existing .gitmodules file which storm-contrib authors may find useful, the second results in a simpler final state which will be usable by all.
