Some of the samples are more like pure integratiuon tests (I wouldn't
use them to copy code into a real app). So I put them with the other
"test" projects.
In a Spring test user can add this annotation to run stubs
rather than rely on auto configuration (which might not be
welcome outside a test).
Fixes gh-33
to org.springframework.cloud from org.springframework.cloud.contract
also stopped running an http server if the contract doesn't support it
added back stub runner modules
