STAC 1.1: invalid metadata returned

[jdries]

I ran a job that produced STAC 1.1 metadata, but except for the version, most metadata is still a weird combo of 1.0 and 1.1 things:

What I see here:

openeo-python-driver/openeo_driver/views.py

Line 1407 in 940354f

def _get_job_result_item11(job_id, item_id, user_id):

Is that the method to retrieve STAC 1.1 item metadata seems to do too much: in 1.1 code paths, the metadata already contains the full item metadata, and the webapp should not somehow do work to reconstruct it, simplifying the code...

[jdries]

The 'raster:bands' property from 1.0 should be fixed over here:
https://github.com/Open-EO/openeo-geopyspark-driver/blob/9c12a9fffb599c8141eae6862bf2e83dfe1f22d7/openeogeotrellis/deploy/batch_job_metadata.py#L280

To immediately include statistics in the 'bands' property of the asset. That should avoid all the duplication that is present in the asset.

STAC documentation shows how 1.1 should look like:
https://github.com/stac-extensions/raster/blob/main/examples/item-sentinel2.json
