The mTLS migration task in the docs was updated to use
PeerAuthentication instead of Policy and DestinationRules, but the
tests were never updated. This updates the test script to be inline
with the docs.
The `TestTCPTrafficShifting` test script relies on fetching the port
named "tcp" on the istio-ingressgateway service, but that port is not
present in the default installation profile -- only in the demo
profile. This patches the service to add the port in the setup
script, and also fixes the usage of `nc` in the test script.
