Prepares to fetch labels associated with the given edge type. For
EdgeType::UNDIRECTED, labels associated with both edges of the sibling
pair will be returned. "edge_type" is a parameter (rather than using
g.options().edge_type()) so that clients can explicitly control whether
labels from one or both siblings are returned.
