RequestValidatorTestCase: Tests for the request validators 

Make a general test with all the cases, like request
advertised/unadvertised tips, reachable/unreachable from those tips,
commits/blobs.

Implement specific validator tests as subclasses. Each test provides the
validator instance and tells what cases are valid.
