Add Support for Sample.sequencing_center

[torstees]

A sequencing center represents the group that performs the actual sequencing. This is not specific to a ResearchStudy, since the same center may be used by many studies and I imagine it is possible that a single study may have sequences that were generated at different centers.

If we use the KF approach where a Task represents the concept of genotyping, where input represents the platform and sample level information and output are the final products at an aggregate level (as opposed to individual genes or variants), they are using Task.owner to reference the organization.

Example from Kristin's example data, FD:

  {
    "host": "http://localhost:8000",
    "type": "sequencing_center",
    "body": {
      "resourceType": "Organization",
      "id": "FD",
      "meta": {
        "profile": [
          "http://hl7.org/fhir/StructureDefinition/Organization"
        ]
      },
      "identifier": [
        {
          "system": "urn:ncpi:unique-string",
          "value": "Organization|FD"
        }
      ],
      "name": "FD",
      "active": "true"
    }
  },

The Task.owner or DiagnosticReport.performer would work I expect. Setting up an organization feels right either way.
