<fix>[mn]: synchronize hash ring operations

[zstack-robot-2]

ZSTAC-86294

Summary

Backport the ZSTAC-78182 zstack fix to 5.4.10.

Root Cause

Management node lifecycle reconciliation can race with lifecycle callbacks, causing NodeHash/Nodes inconsistency and task stalling.

Fix

Synchronize ResourceDestinationMaker hash ring operations and serialize management node lifecycle reconciliation with two-round missing-node confirmation.

Verification

• Cherry-pick to upstream/5.4.10 completed cleanly.
• git diff --check upstream/5.4.10..HEAD passed.
• Full regression was not run locally.

Warning

Review limit reached

You’ve reached a temporary PR review limit under our Fair Usage Limits Policy.

Your recent review volume is higher than typical usage, so adaptive limits are currently applied.

Next review available in: 50 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
