Move backend tests into their projects

Instead of having a single project which tests all backends, each
backend now implements a http test trait along with a streaming test
trait if it supports streaming. The test http server has been moved into
its own project and is started automatically before running a backends
test. This allows each backend to be tested without the possibility of
dependency eviction from another backend or the test http server. It
also has the side effect of parallelizing the tests providing a speed
up when run with multiple cores.
