Determine cluster_definer for cluster of size 1 automatically/in query

[mdragaschnig]

if number_of_addresses_in_cluster == 1 then cluster_definer=true

Is this something that should be done in the REST interface? Or would it be better to move it into the tagstore. Eg. when we redesign the public interface (graphsense/graphsense-tagpack-tool#94)?

Conceptually it would make sense to move this to the tagstore, i.e. closer to where the non-trivial cluster_definers are decided upon.
