Replace test-harness submodule with spec submodule #743
Description
The evaluation.feature gherkin file is currently being supplied from the test-harness module. In our efforts to remove all flagd-related dependencies from the SDKs, this gherkin is now available in the spec (with a few minor changes).
Delete the test-harness submodule and replace it with a submodule for the spec, and update the scripts in the package.json to get the evaluation.feature from that new location. You may need to make a few minor changes to the test implementation to match minor language changes in the gherkin.
