**User story**
Add support for the R4 [primitive types](https://www.hl7.org/fhir/datatypes.html) mapping to Date search type.
**Acceptance criteria**
1. Support is visible at the /metadata endpoint
1. Canonical urls are indexed correctly
1. Verify resources can be searched by Date. e.g. CarePlan.activity.detail.scheduled(Timing,FhirString), ChargeItem.occurrence(Timing)

Research direction
Start at the /metadata endpoint and trace existing R4 search parameter mappings for Timing=>Date and String=>Date. Check canonical URL indexing and searches for CarePlan.activity.detail.scheduled(Timing,FhirString) and ChargeItem.occurrence(Timing); done means metadata advertises support and both Date searches work.
