interop-testing: Modernize stress test channel creation 

OverrideAuthority() is the modern alternative to rewriting the
InetAddress, and can also work if we change the channel creation to use
target strings instead. We can use test CAs now without resorting to the
Netty-specific APIs. After this change, only 4 classes in
interop-testing depend on Netty.
