auto-polarization: apply only to specific collections

[bossie]

https://discuss.eodc.eu/t/sentinel1-card4l/614/2

Collections backed by SHub are eligible for auto-polarization only by virtue of having some of these bands: HH, HV, VV or VH.

This includes the SENTINEL1_CARD4L collection, but it doesn't support filtering by polarization at all.

Adding an "auto_polarization": true flag (defaults to false) in the "_vito"/"data_source" part of the appropriate collections should work but checking if "_vito"/"data_source"/"collection_id" == "sentinel-1-grd" is also an option.

This is deployed now on https://openeo-dev.vito.be The following proces_graph did give a successful result:
