Some HistoryService interfaces have incorrect return types.

[kevinpeterson]

As per the CTS2 spec, history services should return the full resource, not a summary or directory entry. The following services incorrectly return a directory entry:

edu.mayo.cts2.framework.service.profile.association.AssociationHistoryService
edu.mayo.cts2.framework.service.profile.codesystem.CodeSystemHistoryService
edu.mayo.cts2.framework.service.profile.codesystemversion.CodeSystemVersionHistoryService
edu.mayo.cts2.framework.service.profile.conceptdomain.ConceptDomainHistoryService
edu.mayo.cts2.framework.service.profile.map.MapHistoryService
edu.mayo.cts2.framework.service.profile.mapentry.MapEntryHistoryService
edu.mayo.cts2.framework.service.profile.valueset.ValueSetHistoryService
