Subgraph (#375)

See subgraph/README.md for instructions on how to deploy the subgraph locally.

- Add `subgraph/` to the workspaces.
- A script, `./deploy-subgraph`, can be used to deploy the subgraph in a
  convenient way. See `--help` for details.

Some context:

- The subgraph uses data source templates [1] for the collateral contracts.
- The script can update the collateral registry address in the
  `subgraph.yaml` if it doesn’t match the one found in the latest
  deployment context.
- In `./deploy-subgraph`, only the local preset is implemented for now.
