Proposed Changes

Add two new Ansible modules for managing Nexus Dashboard multi-tenancy resources using the new pydantic-based architecture:

nd_infra_tenant — Manage tenants on Cisco Nexus Dashboard

• CRUD operations for tenants via the ND Infra API (/api/v1/infra/tenants)
• Fabric association management via the ND Manage API (/api/v1/manage/tenantFabricAssociations)
• Multi-API orchestrator that coordinates tenant lifecycle (infra) with fabric association reconciliation (manage) transparently through the state machine
• Supports merged, replaced, overridden, and deleted states

nd_infra_tenant_domain — Manage tenant domains on Cisco Nexus Dashboard

• CRUD operations for tenant domains via the ND Infra API (/api/v1/infra/tenantDomains)
• Groups tenants together by referencing tenant names
• Supports merged, replaced, overridden, and deleted states

Test Notes

• 347 unit tests pass (pytest tests/unit/ -v), including 38 new endpoint tests covering infra tenants (16), infra tenant domains (16), and manage tenant fabric associations (6)
• Integration tests cover all four states (merged, replaced, overridden, deleted) with check mode, normal mode, and idempotency assertions for both modules
• nd_infra_tenant integration tests include fabric association scenarios: create with associations, update associations, replace with associations, override with associations, and delete with association cleanup
