As a Builder I want a centralized API for Creating & Retrieving Requests so I don't need to use the RN SDK

Considerations

• The caller must trust the Request Node to generate good random data for the paymentReference salt.
• For encrypted requests, the caller must trust the Request Node to encrypt the data on their behalf.
• Would this involve sending channel key over the internet?

Idea: Separate the Graph Node into "write" and "read".

Write part would continue to use REST API built on the Request Node.
Read part could use a new GraphQL API with subscriptions.
