More Filters for Graph Queries

[DnOberon]

Use Case

I have some data and I want to automatically create a graph from it and then query that graph. I know my graph root node's original ID, so I can use the feature added here https://github.inl.gov/Digital-Engineering/DeepLynx/pull/298, awesome! But conceivably, my container could contain more than one node that has this same root node original ID. However, if graph query filters were added for root_node_data_source_id, and root_node_metatype_id it would solve this potential issue. You could confidently query a graph by original node ID, and be sure that your root node is actually what you think it is. And you could also get results for a graph that spans more than one data source.

Impact

More graph query functionality, making it easier for users and reducing their need for post processing graph query results.
