Add option to limit time period on per resource basis

[makampf]

Look up search parameters in FHIR profiles to find field that works as date.

Could be solved using fhir.filter.expression: https://github.com/miracum/kafka-fhir-to-server/blob/master/src/main/resources/application.yml#L69

an expression like:

Bundle.entry.resource.where(resourceType='Encounter').exists(period.start > '2011')

multiple resource types could be encoded in the same expression but may not be very readable. Instead, a new feature could be added that accepts a list of expressions (matches-any-expression).
