Summary: Antlr grammar has been updated to support putting edge types after the BFS symbol. Planner collects edge type filters for BFS and inlines them in the operator by joining the filter with the user input BFS filter itself. This requires no change from the standpoint of the operator. On the other hand, in order to use the faster lookup by a single edge type, `ExpandBreadthFirst` operator now accept an optional edge type. The edge type is passed from the planner only if the user is filtering by a single type. Unit tests as well as tck have been updated.
