viz provide means to (auto)select the properties for cluster, node and rel-weight

We provide a dropdown for rel properties, but we don't distinguish between rel and node properties: https://github.com/neo4j-devtools/neuler/blob/master/src/services/metadata.js#L19

Is it possible to distinguish between the two?

Edit: Silly me, actually it is seems like we can get node properties with apoc.meta.schema as in https://github.com/neo4j-devtools/neuler/blob/master/src/services/metadata.js#L28, so we could look at the difference between the two to get only rel props
