* New @StartStop extension for JUnit 5
This is a new take on our JUnit 5 extension. Rather than creating and managing
the MockWebServer instance in the extension, we let the user create it and all
the extension does is manage the lifecycle.
Note that this annotation doesn't require any external configuration - it doesn't
need a system-property to opt-into 'automatic' extensions, and it doesn't require
a class-level extension either.
