[BUG] Test server datasets/get_data results in TooManyRedirects

[L-Agbaria]

Using get_data() on the test server results in more than 30 redirects, accessing the dataset directly through the site and querying like the API like normal both function well.

Code snippet:
import openml
openml.config.server = "https://test.openml.org/api/v1/xml"
dataset = openml.datasets.get_dataset("iris")
X, y, categorical_indicator, attribute_names = dataset.get_data()

Output:
--> X, y, categorical_indicator, attribute_names = dataset.get_data()
TooManyRedirects: Exceeded 30 redirects.

All the minio endpoints themselves did not work, it seemed, from the test server. So this was not a problem in openml-python, already a request to any endpoint in minio (e.g., https://test.openml.org/minio/datasets/0000/0123/quake.arff), failed.

The problems seemed to be in the NGINX ingress nginx.ingress.kubernetes.io/force-ssl-redirect: "true". I changed that to

    nginx.ingress.kubernetes.io/force-ssl-redirect: "false"
    nginx.ingress.kubernetes.io/ssl-redirect: "false"

@L-Agbaria , could you check that this indeed works for you? If so, would you close the issue?
