Update: This milestone is postponed to be completed after the refactoring of the project.

This milestone makes the second iteration of the graph network subgraph fed by substreams. Data covered in this iteration is Curator entity, signalled and unsignalled tokens, and batch update experimentation for total delegated tokens for delegators. This milestone includes deploying the subgraph to graph node, testing the subgraph by comparing values with the original subgraph, and updating the docs accordingly.
