Title: add :trail option for starting the cluster in... well, trailing mode.

- the current implementation assumes that topics should be read from the
starts but we have use cases where we only cares about what comes
next (especially for topics where we keep messages for long periods
of time)
- initially wanted to support an :offset option butit became too messy too
quickly
