Proposed Changes

Add new nd_manage_fabric_ai_ibgp_vxlan and nd_manage_fabric_ai_ebgp_vxlan modules for managing AI/ML iBGP and eBGP VXLAN fabrics on Nexus Dashboard.

New files:

• plugins/module_utils/models/manage_fabric/manage_fabric_ai_ibgp_vxlan.py — Pydantic model with AimlVxlanIbgpManagementModel inheriting from VxlanIbgpManagementModel (overrides type discriminator to aimlVxlanIbgp), and FabricAiIbgpVxlanModel with shared fabric properties, Literal[FabricTypeEnum.AIML_VXLAN_IBGP] type discriminator, and single identifier strategy on fabric_name
• plugins/module_utils/models/manage_fabric/manage_fabric_ai_ebgp_vxlan.py — Pydantic model with AimlVxlanEbgpManagementModel inheriting from VxlanEbgpManagementModel (overrides type discriminator to aimlVxlanEbgp), FabricAiEbgpVxlanModel with to_diff_dict() override excluding nxapiHttp, and single identifier strategy on fabric_name
• plugins/module_utils/orchestrators/manage_fabric_ai_ibgp_vxlan.py — Orchestrator reusing EpManageFabrics* endpoints with custom query_all filtering for management.type=="aimlVxlanIbgp"
• plugins/module_utils/orchestrators/manage_fabric_ai_ebgp_vxlan.py — Orchestrator reusing EpManageFabrics* endpoints with custom query_all filtering for management.type=="aimlVxlanEbgp"
• plugins/modules/nd_manage_fabric_ai_ibgp_vxlan.py — Module supporting merged, replaced, overridden, and deleted states
• plugins/modules/nd_manage_fabric_ai_ebgp_vxlan.py — Module supporting merged, replaced, overridden, and deleted states

Modified files:

• plugins/module_utils/models/manage_fabric/enums.py — Added AIML_VXLAN_IBGP = "aimlVxlanIbgp" and AIML_VXLAN_EBGP = "aimlVxlanEbgp" to FabricTypeEnum

New tests:

• tests/integration/targets/nd_manage_fabric/tasks/fabric_ai_ibgp.yaml — Integration tests covering create, update, replace, override, delete, check mode, and idempotency
• tests/integration/targets/nd_manage_fabric/tasks/fabric_ai_ebgp.yaml — Integration tests covering create, update, replace, override, delete, check mode, and idempotency
• tests/integration/targets/nd_manage_fabric/tasks/main.yaml — Added AI iBGP and AI eBGP test includes
• tests/integration/targets/nd_manage_fabric/vars/main.yaml — Added AI iBGP and AI eBGP test variables

Test Notes

• 309 unit tests passing (0 new + 309 existing), 0 failures
• Integration tests cover: single fabric creation, merged updates (idempotency, partial updates), replaced state (idempotency, full replacement with defaults validation), overridden state, deletion with idempotency, and check mode for all states
