ROSAENG-62424 have a dedicated provisioning_failure_notify for spot and send dedicated SL

What this PR does / why we need it?

This PR is to exclude the spot nodepool in the provisioning_failure_notify recording rule and make it for on-demand nodepool.

Originally, the recording rule assumes the nodepool are all on-demand, so nodes should all be able to provision, otherwise there could be a problem.

But for spot instances, it is likely not to be able to provision due to pricing or AWS capacity, which is expected. We don't want to trigger alerts if the nodepool is running spot.

For the spot instance nodepool, we add provisioning_failure_notify_spot delicately, and add a SL template for spot nodepool.

Special notes for your reviewer:

Validated, steps:

• Create a HCP cluster in staging.
• Create a nodepool manually in the HC namespace in the corresponding MC.
• Go to Grafana and check the metrics.
• Because I can provision the spot nodepool smoothly, I changed the PromQL from < to == to see how the recording rule behave.

(hypershift_nodepools_available_replicas / hypershift_nodepools_size == 1)

(keep the other conditions same as this PR)

• Without the change in this PR, I can see all nodepools including spot.
• With the change in this PR, the spot nodepool is excluded, the other nodepool / other clusters remain the same.

Pre-checks (if applicable):

• Tested latest changes against a cluster

Walkthrough

The monitoring rules now separate Spot and on-demand nodepool provisioning failures. A warning alert and ManagedFleetNotification resource handle Spot failures with dedicated content and a 24-unit resend interval.

Changes

Spot nodepool monitoring

Layer / File(s)	Summary
Recording rules and alert routing deploy/sre-prometheus/ocm-agent/obo-monitoring/100-nodes-not-joining-nodepool.PrometheusRule.yaml	The general recording rule excludes Spot nodepools. A Spot-specific recording rule and warning alert identify Spot provisioning failures. The existing alert now identifies on-demand failures.
Spot notification resource deploy/ocm-agent-operator-managedfleetnotifications/nodepool-provisioning-failure-spot.yaml	The new ManagedFleetNotification defines Spot-specific warning content, support guidance, a 24-unit resend interval, and limitedSupport: false.

Estimated code review effort: 2 (Simple) | ~10 minutes

Mergeability Score: ⚪ Minimal · up to c07ab

This change excludes expected spot-capacity provisioning failures from the relevant notification rule while preserving detection for other nodepools. No actionable merge-blocking risk remains beyond normal checks and review.

LGTM - defer to other MCC folks to take a look as well.

This alert is used by ocm-agent-operator to send a service log to customers telling them their nodes aren't provisioning. Wouldn't they want to know that is the case, regardless of spot or not?

SRE wouldn't care if they had no nodes because spot requirements weren't meant, but this alert appears to be customer focused unless I am misunderstanding it.

@joshbranham Good point - You're right that this change would also suppress the customer-facing NodePoolFailureNotification, not just the SRE paging path.

From the Jira, this looks intentional, with Spot capacity/availability being treated as an expected condition and the service log considered potentially noisy. The key question to me is whether suppressing the customer notification for all Spot nodepools was already discussed and agreed as the intended behavior.

@feichashao - please correct me if I’m misunderstanding, or confirm if this was already aligned.
