feat(interactive): Refactor `QueryParams` in physical layer, use edge triplet to represent edge label.

We all know that an edge label triplet `(src_label, edge_label, dst_label)` uniquely defines a relationship. However in current compiler's physical layer, The QueryParams only contains a `edge_label, the `src_label` and `dst_label` is presented in `metadata`.

Ideally, We shall put edge label triplet into `QueryParams`, and engines shall not get the label info from metadata.
