Update end to end tests

Use the testing harness that uses schema webhook instead of runscope.

Other relevant changes:
- Moved e2e tests from Travis.yml to Makefile
- Refined list of files to include in gems, so that other files in
directory don't cause installation problems (like .gem files)
- Remove old e2e only code.
