Support parametrization of properties in UDP

[VincentVerelst]

The process graph below is part of a UDP with three parameters: spatial_extent, temporal_extent and orbit_state. The latter is a string that can either be "DESCENDING" or "ASCENDING".

"loadcollection1": {
      "process_id": "load_collection",
      "arguments": {
        "id": "SENTINEL1_GRD",
        "properties": {
          "sat:orbit_state": {
            "process_graph": {
              "eq1": {
                "process_id": "eq",
                "arguments": {
                  "x": {
                    "from_parameter": "value"
                  },
                  "y": {
                    "from_parameter": "orbit_state"
                  }
                },
                "result": true
              }
            }
          }
        },
        "spatial_extent": {
          "from_parameter": "spatial_extent"
        },
        "temporal_extent": {
          "from_parameter": "temporal_extent"
        }
      },
      "result": true
    }

Running this UDP results in the following error:
OpenEoApiError: [400] PropertyConditionInvalid: Expected parameter 'value' but got 'orbit_state'
job id: cdse-j-241114ee6489428aad7351dd62b881c3

It seems the parametrization of properties, like orbit_state is not yet supported in the backend. Hence the request for its support here.

parameterization of spatial_extent and temporal_extent should indeed already be covered

property filtering indeed does not support parameterization yet.
To be added to usage of this helper:

openeo-python-driver/openeo_driver/filter_properties.py

Lines 13 to 17 in 06f7670

	def extract_literal_match(condition: dict, parameter_name="value") -> Dict[str, Any]:
	"""
	Turns a condition as defined by the load_collection process into a set of criteria ((operator, value) pairs).
	Conditions are currently limited to processes "eq", "lte" and "gte" so they will be turned into a single criterion.

@VincentVerelst can you also state for which project this is important (for planning purposes)?

@VincentVerelst can you also state for which project this is important (for planning purposes)?

This would be needed for the WorldCereal project.

@JeroenVerstraelen, this one is needed for WorldCereal. Is it possible to take it up in one of the next sprints?
