Code coverage improvements (#121)

These are test-only changes to improve code coverage so I'll merge directly.  Please review the commit and I'll pickup those changes in the next iteration.

* Add integration test batch file

* Exclude Linux and MacOS from Windows code coverage builds

* Enable code coverage for test driver e2e tests

* Use the windows only build for code coverage runs
