441-454: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick winAdd regression cases for limit updates and unset limits.
These assertions validate only the initial snapshot. They do not prove that changing
Quota.Limitupdateshami_resource_quota_limitunder the same{namespace, quota_name}labels. They also do not verify thatLimitSet == falsedoes not export an absent limit as zero.Add a test that changes a quota limit and expects only the new value for the existing label set. Add an unset-limit case to protect the presence contract.
Also applies to: 470-483

- Around line 309-311: Guard the new quotaLimitDesc metric emission with
q.LimitSet so absent limits are not exported as zero; keep the existing
sendMetric error logging unchanged. Do not use continue, ensuring the existing
usage and legacy metric emissions still run for every quota.

What this PR does / why we need it: In cmd/scheduler/metrics.go, resource quota limits were previously exposed only as a string label (
limit="100") inside hami_resource_quota_used.This caused two problems:
This PR adds hami_resource_quota_limit as a dedicated numeric gauge metric with labels
[]string{"namespace", "quota_name"}.hami_resource_quota_usedand legacyQuotaUsedare kept unchanged for backward compatibility.Which issue(s) this PR fixes:
Fixes #2713
