In preparation for later changes, adds tests for the existing
domain verification flow for auto verified app links.
Implements a proxy verifier which saves incoming requests to
a file on disk which can be read back later by another call
from the host side test to send a success/failure code.
This tests some basic known success/failure cases, as well as
verifies the presence of bugs, which have been marked with TODOs
against the feature bug number, to be fixed with later work.
Also migrates manual test cases from
I200d85085ce79842a3ed39377d1f75ec381c8991.
