📝 Description

This pull request adds support for fields related to LKE APL, including two new property methods under LKECluster to ease accessing the APL console.

✔️ How to Test

The following test steps assume you have pulled down this PR locally and run make install.

Unit Testing

make testunit

Integration Testing

make TEST_COMMAND=models/lke/test_lke.py::test_lke_cluster_with_apl testint

Manual Testing

1. In a linode_api4-python sandbox environment (e.g. dx-devenv), run the following:

import os

from linode_api4 import LinodeClient, LKEClusterControlPlaneOptions


def main():
    client = LinodeClient(os.getenv("LINODE_TOKEN"))

    cluster = client.lke.cluster_create(
        region="us-mia",
        label="apl-test",
        kube_version="1.31",
        node_pools=[
            client.lke.node_pool("g6-dedicated-4", 3)
        ],
        control_plane=LKEClusterControlPlaneOptions(
            high_availability=True,
        ),
        apl_enabled=True
    )

    print("Cluster:", cluster)
    print("APL Enabled:", cluster.apl_enabled)
    print("APL Console URL:", cluster.apl_console_url)
    print("APL Health Check URL:", cluster.apl_health_check_url)


if __name__ == "__main__":
    main()

2. Ensure the output looks similar to the following:

Cluster: LKECluster: 316845
APL Enabled: True
APL Console URL: https://console.lke316845.akamai-apl.net
APL Health Check URL: https://auth.lke316845.akamai-apl.net/ready

Hardcoding the URLs here feels a little gross but this is how it's done in Cloud Manager: https://github.com/linode/manager/blob/ecc0357e61d958c2e04bebbbcbaedccc70562898/packages/manager/src/features/Kubernetes/KubernetesClusterDetail/APLSummaryPanel.tsx#L39

LGTM, tests passing locally.

Side note: In order to test APL changes, beta program enrollment is required at the moment in CM

Tested and works well on my end, nice work!
