OCPCLOUD-2710: Extend AWS metadata service options in MAPA

[RadekManak]

Add httpEndpoint, httpPutResponseHopLimit, and instanceMetadataTags fields to MetadataServiceOptions to bring parity with CAPA. This allows users to configure additional aspects of the AWS Instance Metadata Service (IMDS) on machine instances, improving backwards compatibility and reducing conversion errors when these options are used in CAPA.

New fields:

• httpEndpoint: Enable/disable HTTP metadata endpoint (Enabled/Disabled)
• httpPutResponseHopLimit: Configure metadata token hop limit (1-64)
• instanceMetadataTags: Enable/disable instance tag access from metadata

📝 Walkthrough

Walkthrough

This pull request extends the MetadataServiceOptions structure in the AWS machine provider configuration by introducing three new fields and two new enum types. HTTPEndpointState and InstanceMetadataTagsState enums are added with Disabled and Enabled constants. The MetadataServiceOptions struct gains three new fields: HTTPEndpoint (HTTPEndpointState pointer), HTTPPutResponseHopLimit (int64 pointer), and InstanceMetadataTags (InstanceMetadataTagsState pointer). Corresponding generated files for deep copying, Swagger documentation, and OpenAPI schema definitions are updated to reflect these additions.

301-309: Verify hop-limit marker syntax to ensure CRD validation is emitted.

Line 306-307 uses Minimum=1 / Maximum=64 while nearby validations use :=. Please confirm controller-tools accepts this form (or align to the := style) so the range is enforced.

🔧 Proposed alignment with existing marker style

🔇 Additional comments (4)

machine/v1beta1/types_awsprovider.go (1)

268-286: IMDS enum additions are clear and consistent.

Line 268-286 adds typed states mirroring AWS values; this keeps the API explicit and readable.

machine/v1beta1/zz_generated.swagger_doc_generated.go (1)

147-153: Swagger docs updated for IMDS options.

Lines 147-153 reflect the new metadata fields and updated authentication semantics; matches the type changes.

machine/v1beta1/zz_generated.deepcopy.go (2)

82-82: DeepCopy now clones MetadataServiceOptions.

Line 82 switches to DeepCopyInto, preventing pointer aliasing after adding optional IMDS fields.

---

1484-1499: DeepCopy handles new IMDS fields correctly.

Line 1485-1499 allocates and copies the new pointer fields as expected.
