As discussed offline, let's change the API of the testing method (and router implementation) to take an actual and expected circuit with the same set of qubits, along with a qubit_map that maps the initial qubits of actual to it's final qubit mapping. As a fallback, if the qubit_map is not specified, the method can potentially try to construct a qubit map by looking at the swaps operations in the actual circuit.

@tanujkhattar I've made the changes we discussed without the fallback strategy as a v1. I can follow up with that with another PR once we have a fully functioning basic routing implementation pushed to Cirq.
