Adding a generic type parameter for a runtime provider to Recursor and RecursorDnsHandle would improve the recursor's testability. This would allow use of a mock runtime in unit tests, simulating multiple remote name servers, which would let us test scenarios that can currently only be tested in the conformance test. This would also let us write tests that inspect the state of the recursor's cache after handling queries.
