Implement access_id method to fetch via /object/{id}/access/{access_id}.

[uwwint]

This implements the access_id method in DRS, as per: https://ga4gh.github.io/data-repository-service-schemas/preview/develop/docs/#tag/Service-Info/operation/GetServiceInfo
at least one of access_url or access_id should be represented. Some argue that either should be the case ga4gh/data-repository-service-schemas#360
whatever the final resolution will be on the ticket - In the absence of access_url using the access endpoint is definitely up to spec ;).

Uwe
