I left it out of this PR on purpose. Figured we won't be enabling the Bridge any time soon, anyway. I can add it to the manifest files, though.

I think we need to still run the unit tests with bridge enabled in the ci. Otherwise they won't be maintained and will rot and potentially be a big headache later.

added a CI task to run eth bridge tests
