FOCOM API: Adding openapi file

[JohnKeeneyEST]

The FOCOM (Federated O-Cloud Cluster Orchestration Management) North Bound Interface (NBI) provides a REST API for managing the complete lifecycle of FOCOM infrastructure resources. This interface enables administrators and orchestrators to declaratively manage O-Cloud configurations, cluster templates, and provisioning requests through a Git-backed, revision-controlled system using Nephio Porch and GitOps synchronization (ConfigSync/Flux).

The FOCOM NBI implements a draft-validate-approve workflow that ensures safe infrastructure-as-code management, with Git serving as the source of truth for FOCOM resources. This approach provides full audit trails, self-healing capabilities, while maintaining clear separation between the northbound management interface and southbound O2IMS integration.

Hi @JohnKeeneyEST. Thanks for your PR.

I'm waiting for a nephio-project 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.
