Include error from backend service when searching with invalid params

[amarandon]

Example

from eodag import EODataAccessGateway

dag = EODataAccessGateway()
dag.set_preferred_provider("dedl")

search_criteria = {
        "productType": "CAMS_EAC4",
        "start": "2024-09-01",
        "end": "2024-08-01",  # *** BEFORE START DATE ***
        "geom": {"lonmin": 1, "latmin": 43, "lonmax": 2, "latmax": 44},
        "count": True,
        "provider": "dedl",
        "raise_errors": True,
}

dag.search(**search_criteria)

When running this code, a RequestError gets raised:

[...]
eodag.utils.exceptions.RequestError: ('Skipping error while searching for dedl StacSearch instance', 
'400 Client Error: Bad Request for url: https://hda.data.destination-earth.eu/stac/search')

However this is missing details returned by the backend services.

If we run the same code with increased logging:

from eodag import EODataAccessGateway, setup_logging
setup_logging(3)

dag = EODataAccessGateway()

dag.set_preferred_provider("dedl")

search_criteria = {
        "productType": "CAMS_EAC4",
        "start": "2024-09-01",
        "end": "2024-08-01",  # *** BEFORE START DATE ***
        "geom": {"lonmin": 1, "latmin": 43, "lonmax": 2, "latmax": 44},
        "count": True,
        "provider": "dedl",
        "raise_errors": True,
}

dag.search(**search_criteria)

Then we can see useful details being logged:

[...]
2024-10-08 15:31:26,929 eodag.search.qssearch            [DEBUG   ] b'{"description":"1 error(s). datetime: Value error, Invalid datetime range, must match format (begin_date, end_date)"}'
[...]

This info should be included in the exception text.
