The Open API schema previously did not reflect the response or the request schema format that was required to create or show BI rules. This werk addresses this issue.

Previously, when creating or getting a BI rule, via the REST-API, the schema for host_label_groups or service_label_groups looked similar to the following:

    "host_label_groups": [
        [
            "and",
            [
                ["and", "mystery/switch:yes"],
                ["or", "mystery/switch:no"],
            ],
        ],
    ]

This did not match the schema documented in the Open API docs. To fix this, we have now changed the format to the following

    "host_label_groups": [
        {
            "operator": "and",
            "label_group": [
                {"operator": "and", "label": "mystery/switch:yes"},
                {"operator": "or", "label": "mystery/switch:no"},
            ],
        },
    ]

This also aligns with other endpoints that use our new host_label_groups or service_label_groups, for example the rules endpoints.

As this is a breaking change, user scripts should be adjusted accordingly.
