What does this PR do?

Adds Service Level Objective (SLO) as a supported DatadogGenericResource type.

This includes:

• the CRD enum update a generic-resource: 6daebcb
• SLO handler with create/get/update/delete/state refresh support: 3ad8251
• docs, and a sample manifest: 94fe5b2
• small update to dev guide: 3f150bd

Motivation

https://datadoghq.atlassian.net/browse/CONTP-1585

Users can already manage SLOs through the dedicated DatadogSLO CRD, but DatadogGenericResource should also support SLOs so users can manage the API object directly from JSON and benefit from DDGR's generic reconciliation flow.

Additional Notes

SLO status refresh uses the SLO search endpoint with the SLO name from spec.jsonSpec, then filters results by the Datadog SLO ID stored in .status.id before surfacing overall_status[].state into .status.state.

Minimum Agent Versions

No minimum Agent or Cluster Agent version is required.

• Agent: N/A
• Cluster Agent: N/A

Describe your test plan

• Deploy the Operator with DatadogGenericResource enabled.
• Apply examples/datadoggenericresource/slo-sample.yaml.
• Verify in the Datadog UI that the SLO is created.
• Edit the DDGR manifest with k edit ddgr ddgr-slo-sample and change the warning threshold.
• Verify in the Datadog UI that the warning threshold update is live.
• Verify the DDGR status with k get ddgr.

  ╰─❯ k get ddgr
