add features to project config (#120)
* add version 4 to the Project Config. Add features to the Project Config * add helper methods to ProjectConfigTestUtils to create a list or map of elements * alphabetize mappings and parameters in ProjectConfig. add feature key mapping * update v4 test datafile with launched experiment * refactor feature to featureFlag
