JSONSliceMetrics returns the slice of metrics as a string containing a JSON array listing those metrics.

ListAllMetrics interates through the host:port strings given in servers contact those buckyd daemons, gets the list of all known metrics on that server, returns a map of server => list of metrics.

ListJSONMetrics queries buckyd daemons specified in servers for all metrics known to that buckyd daemon and that are present in the io.Reader interface which points to a data source containing a JSON array.
