Changes to make availableScopeValues map available to the scope picker.
Changes to make availableScopeValues map available to the scope picker.

Additional TODO’s:
1. Check the availableScopeValues map when the user selects a scope key. If the map contains the selected key, make the scope value field a dropdown that contains the available scope values.
2. Pre-populate the scope picker with scope that has already been added.
3. Fix scope picker save, which is erroring now.
