------------------------------------------------------------------------
I haven't thought it through, but there may be potential for issues down that
route since the commitlog is measuring the last time the node was written, not
up, so edge cases may exist for low write traffic clusters.

> As already discussed on ML, it would be nice to have a service which would
> periodically write timestamp to a file signalling it is up / running.
> Then, on the startup, we would read this file and we would determine if there
> is some table which gc grace is behind this time and we would fail the start
> so we would prevent zombie data to be likely spread around a cluster.
