Fix race condition when looking up reaper (ryuk) container (#2508)

* If the ryuk container has a health status, wait for a healthy container before returning.

* Use docker/types for health status, but also check for the zero value.

* Wait for the ryuk port to be available in case the container is still being started by newReaper in a separate process.

A race between newReaper and lookUpReaperContainer occurs:
- newReaper creates the container with a ContainerRequest.WaitingFor = wait.ForListeningPort(listeningPort)
- newReaper starts the container
- lookUpReaperContainer obtains the container and returns.
- newReaper invokes the readiness hook wait.ForListeningPort(listeningPort).

* Fix whitespace.

* chore: simplify

* chore: make lint

* chore: change emoji in log output when waiting

* chore: move inside reuseReaper
