CSA claims HAPI 3.0, but does not support dataset=

[rweigel]

Works:
https://csatools.esac.esa.int/HapiServer/hapi/datset?id=C4_CP_WHI_PASSIVE_ACTIVE

Throws 500 and does not return valid HAPI JSON:
https://csatools.esac.esa.int/HapiServer/hapi/datset?dataset=C4_CP_WHI_PASSIVE_ACTIVE

If HAPI 3.0, autogenerated links at https://csatools.esac.esa.int/HapiServer/hapi should use dataset instead of id.
