There's no need to have a dormant container because the traffic-agent can serve as the replacement itself. That way, there's no need to redirect ports either, which means that there's no need to rename ports or use an init-container. An annotation is added to the pod to cater for when multiple injections happen due to replace-policy, so that injections that follow the one when an app-container is removed can reproduce the traffic-agent container, taking its ports, mounts, and environment into account.

It is now possible to intercept multiple ports with one single invocation of `telepresence intercept` by just repeating the `--port` flag. Signed-off-by: Thomas Hallgren <thomas@tada.se>

The `Eventually` function will always wait for its initial tick-delay. This commit ensures that the PingInterceptedEchoServer pings immediately and then uses Eventually if that ping fails. Signed-off-by: Thomas Hallgren <thomas@tada.se>
