> Probe.sh broadcasts requests to all reachable nodes in any cluster. The only way to restrict the reach of a probe request is to pass a time-to-live to it, but that's (a) too coarse-grained and (b) doesn't work for TCP.
> We should therefore be able to define a list of clusters and a list of nodes to which we want to restrict the request. Both clusters and nodes should be simple regexps. 
> The filter is sent with the probe request. Nodes which don't pass the filter simply discard the request.
> Example:
> {noformat}
> probe.sh -cluster DrawCluster,cluster-*{noformat}
> This restricts the request to the {{DrawCluster}} and any cluster starting with {{cluster-}}.
> {noformat}
> probe.sh -nodes cluster-*
> {noformat}
> Sends the request only to nodes with a name starting with {{cluster}}.
