Update supported attributes/qualifiers

[shuchenliu]

Jan release adds a couple of more attributes and qualifiers on both edges and nodes. Constraints generation process should be updated to support these newly added fields.

The current attribute generation logic hinges on prior knowledge of attributes on nodes and edges, somewhat incompatible with our goal of keeping the retriever module as agnostic to the upstream data as possible. Per internal discussions, the plan going forward is:

1. Disable pre-query attribute constraints generation to favor a post-pass filtering on query results returned;
2. Develop metadata-based type inferring module for attribute fields to replace the existing, explicitly defined data types;
3. Substitute or configure the aforementioned module in step 2 if more direct knowledge becomes available from the DINGO team in the future. At that point, pre-query constraints generation logic can be subsequently re-enabled with the properly configured module.

@shuchenliu Mind if I piggyback Tier 0 implementation for your outline as well? I believe it's the same overall procedure.
