Currently STAC metadata for Sentinel-1, Sentinel-2 and AgERA5 is automatically included when a user creates a STAC collection. It is already possible to include custom metadata.
Change this so that the user can either chose between pre-defined Sentinel-1, Sentinel-2 or AgERA5 metadata, or use their own custom metadata.
Also add validation in case of user customized metadata.
