Resource Catalogue / Discovery - inconsistent naming

[blaziq]

The building block is named "Resource Discovery" in the Architecture documentation but the name is "Resource Catalogue" in the Deployment Guide. From the description in Architecture it seems that Resource Catalogue is only a part of Resource Discovery, the other parts being Dataset Catalogue and API Gateway (currently non-existent because of lack of IAM component, as far as I understand).

It may be unclear to a user that this is the same component or how to access the Dataset Catalogue - also called Data Catalogue (eoAPI) in the same document. Is this simply the STAC endpoint of the Resource Catalogue: https://resource-catalogue.<INGRESS_HOST>/stac?

Please clarify the documentation and use consistent naming throughout different documents and sections.
