docs: // ContainerWait waits until the specified container is in a certain state
  // indicated by the given condition, either "not-running" (default),
  // "next-exit", or "removed".
  //
  // If this client's API version is before 1.30, condition is ignored and
  // ContainerWait will return immediately with the two channels, as the server
  // will wait as if the condition were "not-running".
  //
  // If this client's API version is at least 1.30, ContainerWait blocks until
  // the request has been acknowledged by the server (with a response header),
  // then returns two channels on which the caller can wait for the exit status
  // of the container or an error if there was a problem either beginning the
  // wait request or in getting the response. This allows the caller to
  // synchronize ContainerWait with other calls, such as specifying a
  // "next-exit" condition before issuing a ContainerStart request.
