Update openeo_driver dependency and fix errors with get_log_entries

[JohanKJSchreurs]

Recently the openeo-python-driver was updated to support a minimum log level in the views and functions to retrieve batch jobs logs. Also the openeo-python-client and openeo-geopyspark-driver were updated for this change.
These changes were made to alleviate the problems in issue Open-EO/openeo-python-driver#170 .

However, this change in the python driver is causing some unit tests to fail in the aggregator because the back ends are getting a method argument they don't recognize.

The version of the dependency needs to be upgraded, and some changes will also need to be made in the aggregator to make it compatible.

One example of the relevant exception:

self = <openeo_driver.testing.ApiResponse object at 0x7ff1b311ea00>, status_code = 200

    def assert_status_code(self, status_code: int) -> 'ApiResponse':
        """Check HTTP status code"""
        if self.status_code != status_code:
            message = f"Expected response with status code {status_code} but got {self.status_code}."
            if self.status_code >= 400:
                message += f" Error: {self.json}"
>           raise ApiException(message)
E           openeo_driver.testing.ApiException: Expected response with status code 200 but got 500. Error: {'code': 'Internal', 'id': 'r-f532ca98d7734704a219d63c9c9e2355', 'message': 'Server error: TypeError("get_log_entries() got an unexpected keyword argument \'level\'")'}
