Fix multiple integration test issues

[yec-akamai]

📝 Description

Fix integration test failures seeing in the CI workflow:

1. VPU plan can be unavailable when the region availability endpoint still returns it as available in a certain region. Skip it when the VPU plan is actually unavailable for testing.
2. Add polling to IPs and IPv6 lookup to resolve lags in vpc creations.
3. Switch the linode plan to a more stable one without (or less) occasionally plans unavailable issue.

✔️ How to Test

make test-int TEST_ARGS="-k test_create_vpu"

make test-int TEST_ARGS="-k test_get_vpu"

make test-int TEST_ARGS="-k test_create_vpc"

🟡 Changes recommended

The new skip condition is implemented via a brittle str(e) substring match that can break if ApiError formatting changes, risking continued test flakiness.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

This PR updates the Linode VPU integration-test fixture to skip VPU tests when instance creation fails due to real-time VPU capacity shortages, even if the region availability endpoint reports the plan as available.

Changes:

• Wrap VPU instance creation in a try/except ApiError block.
• Skip the VPU test session when the API indicates the selected VPU plan is not available in the chosen region.

🔵 Needs a closer look

The new polling uses wait_for_condition (which raises on timeout), making the subsequent asserts unreachable and reducing test failure clarity unless adjusted.

• wait_for_condition raises TimeoutError on failure, so the subsequent assert matched_ip is not None is unreachable and you lose the more specific failure message about which IP was missing. Catch the timeout and raise an assertion with the test-specific context instead.

        matched_ip = wait_for_condition(5, 120, resolve_vpc_ip)

        assert (
            matched_ip is not None
        ), f"Expected VPC IP {vpc_ip.address} not found in /vpcs/ips"

test/integration/models/linode/test_linode.py:1077

• Same issue as above: wait_for_condition raises TimeoutError, so assert matched_ipv6 is unreachable and the test loses the helpful message identifying the Linode/VPC. Convert the timeout into an assertion with that context.

        matched_ipv6 = wait_for_condition(5, 120, resolve_vpc_ipv6)

        assert (
            matched_ipv6
        ), f"No VPC IPv6 found for Linode {linode.id} in VPC {vpc.id}"

🟢 Approval recommended

The changes are isolated to integration tests, align with existing test utilities (e.g., wait_for_condition), and improve stability without altering SDK runtime behavior.
