Function TestPublishedPortAlreadyInUse

integration/network/bridge/bridge_linux_test.go:516–540

TestPublishedPortAlreadyInUse checks that a container that can't start because of one its published port being already in use doesn't end up triggering the restart loop. Regression test for: https://github.com/moby/moby/issues/49501
