What problem does this PR solve?

Issue Number: Close #9855

What is changed and how does it work?

Add 'store' label to metric pd_cluster_status in 8.5.

Check List

Tests

• Unit test

Code changes

• Code now emit Gauge metric pd_cluster_status for each store separately and adds label 'store' containing storeId. Previously code aggregated this metric across all stores and then emitted one time.

Side effects

• metric pd_cluster_status now needs to be aggregated in metic system across all stores if you need value across whole cluster.

None

Release note

We added 'store' label to metric pd_cluster_status. This new label contains store ID for which datapoint is emitted. How if you still need the value from this metric for the whole cluster, then you need to aggregate it across all stores

Hi @SerjKol80. Thanks for your PR.

I'm waiting for a tikv member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

@lhy1024 I don't think cherry-pick works here, because this part of code was refactored significantly, thus will have a lot of conficts. Instead I implemented the simial logic in master branch: https://github.com/tikv/pd/pull/9898
