Change http port for NorthBoundIT tests

The NorthBoundIT tests are failing on jenkins due to port http 8080
already in use. I don't know what else would be running on port 8080
on the build machines - maybe a remnant of another test that didn't
cleanup or didn't finish cleaning up in the background. In any event,
I changed the port to 8180 to hopefully avoid the issue so verify
builds can succeed.
