Enrich Observation Diagnostic Result resources with 'Must Support' data so the below test is not skipped.

Test 1.11.20 All must support elements are provided in the Observation resources returned.

Could not find 'identifier', 'performer', 'interpretation', 'note', 'referenceRange', 'referenceRange.low', 'referenceRange.high', 'referenceRange.type', 'referenceRange.text', 'hasMember', 'component', 'component.code', 'component.value[x]' element(s) in the 1 provided Observation resource(s). To prevent this issue, please add the missing must support elements to at least one Observation resource on the server.
