Add Donor Data schemas and Resolvers to GQL server

[joneubank]

Adding the ability to query the data indexed by the Donor Aggregator. This functionality is currently available in the ARGO platform API, but will be moved into this service.

Dependent on the completion of #298

We want to move the schemas and resolvers to query the data indexed by the donor aggregator from the ARGO platform gateway into the GQL server in this service. The schemas should be copied into this service unchanged. Implementing the resolvers may require updates to this service's config and potentially copying other utilities from the platform-api codebase.

Detailed Description

We need to copy the schema and resolvers for two types from the platform api:

1. ProgramDonorSummary - https://github.com/icgc-argo/platform-api/tree/develop/src/schemas/ProgramDonorSummary
2. ProgramDonorPublishedAnalysisByDateRange - https://github.com/icgc-argo/platform-api/tree/develop/src/schemas/ProgramDonorPublishedAnalysisByDateRange

These resolvers come with some built in authorization rules. For the scope of this ticket, leave these unchanged. There are follow-on tickets to add authorization rules to allow access by RDPC admin.

The outcome of this work should have both of these types queryable through the gql server for dcc admin or program submitters.
