feat(interactive): Support sinking all vertices in a path

[zhanglei1949]

Currently Interactive compiler generate path expand plans with path_expand_opt=EndV only. For the paths obtained from a query, only the last vertex is returned to the client/driver.

We shall return the complete information of a path, all vertices or all vertices and edges.
