See comments below (there is a bug that needs to be fixed). I also removed some of your test configuration that you included since some of it was client related, plus we only need 2 mappings to test with anyways (I left two in that looked like test mappings that you might've created that would be good for testing with). For the extract_script_test mappings, it looks like you got some scripts already in there, but I would go through the configuration and make sure you have an example of all possible scripts for the mapping to test extraction with since there are several scripts in mappings and it's possible you missed a few (I would probably ask Sean Ku for help creating a good test mapping since he's familiar with what all the possible scripts are that could get extracted). I'm not sure how many scripts config-manager supports extracting, but we'll want to support importing those ones in particular.

I just rebased the branch. I deleted your old testing configuration in favor of some that I created that have all possible mapping scripts in them so you can test to verify your code works for importing them all.

A few more changes needed, but everything else looks good
