Issue:
Configure x-request-id support in the default ootb examples
We should configure x-request-id correctly for our out of the box examples, and ensure that gateways can easily then integrate their own request tracing.

For vLLM, it would be very desirable to ensure that x-request-id is sufficiently scoped in logs such that we can identify request start, request end, and any related requests (i.e. `POST /v1/completions` or similar should show the request id)

Discussion:
@kfswain: This should be reasonable for a newcomer to handle, we just need to expose x-request-id in logs@delavet: Hi maintainers (●ﾟωﾟ●), I'm Hang Yin from Alibaba Cloud and I would like to start contributing from this issue. Please assign it to me.

+# Conformance Reports for Gateway API Inference Extension
+
+This directory stores conformance reports submitted by various implementations of the Gateway API Inference Extension. This structure closely follows the [kubernetes-sigs/gateway-api/conformance/reports](https://github.com/kubernetes-sigs/gateway-api/blob/main/conformance/reports/README.md).
+
+## How this folder is structured
+
+This folder stores conformance reports organized first by the version of the Gateway API Inference Extension specification they were tested against, and then by the specific conformance profile (e.g., Gateway, EPP, Model Server):
+
+|-- conformance/reports
+|   |-- v0.3.0  # Example extension version
+|   |   |-- gateway  # Conformance profile/category
+|   |   |   |-- my-inference-gateway
+|   |   |   |   |-- README.md
+|   |   |   |   |-- experimental-v1.2.3-default-gateway-report.yaml # Example report file
+|   |   |   |-- another-implementation
+|   |   |   |   |-- README.md
+|   |   |   |   |-- ...
+|   |   |-- epp # Future conformance profile/category
+|   |   |   |-- my-epp-implementation
+|   |   |   |   |-- ...
+|   |   |-- model-server # Future conformance profile/category
+|   |   |   |-- ...
+|   |-- v0.4.0 # Future extension version
+|   |   |-- ...
+
+## Implementation Submissions
+
+Each implementation conformant with a specific profile of a specific version of the Gateway API Inference Extension should have its own folder within the corresponding version and profile directory (e.g., `/conformance/reports/v0.3.0/Gateway/my-implementation/`).
+
+The implementation is the owner of its folder and is responsible for:
+
+1.  Uploading one or more conformance reports (YAML files).
+2.  Maintaining a mandatory `README.md` file within their folder, structured as follows:
+
+    # My Inference Gateway Implementation (Gateway Profile Conformance)
+
+    General information about the My/Implementation project.
+
+    ## Table of Contents
+
+| Extension Version Tested | Profile Tested | Implementation Version | Mode    | Report                                                                     |
+|--------------------------|----------------|------------------------|---------|----------------------------------------------------------------------------|
+| v0.3.0                   | Gateway        | v1.2.3                 | default | [v1.2.3 Gateway report](./experimental-v1.2.3-default-gateway-report.yaml) |
+| ...                      | ...            | ...                    | ...     | ...                                                                        |
+
+    ## Reproduce
+
+    Instructions on how to reproduce the claimed report(s).
+
+### Table of Contents (within Implementation README)
+
+The table of contents within an implementation's `README.md` should contain one row for each submitted report and include the following columns:
+
+* **Extension Version Tested**: The version of the Gateway API Inference Extension specification tested against (e.g., `v0.3.0`). Must correspond to the `gatewayAPIInferenceExtensionVersion` field in the report.
+* **Profile Tested**: The specific conformance profile tested (e.g., `Gateway`, `EPP`, `ModelServer`). Must correspond to the `name` of the profile in the `profiles` list within the report.
+* **Implementation Version**: A link to the GitHub/website page for the specific release/commit of the implementation tested. The version value MUST correspond to the `implementation.version` field in the report.
+* **Mode**: The operating mode of the implementation used for the test run (default is `default`). Must correspond to the `mode` field in the report. If a mode other than `default` is used, the "Reproduce" section must explain how to configure it.
+* **Report**: A link to the corresponding report YAML file. Reports MUST be named according to the pattern: `<Implementation Version>-<Mode>-<Profile>-report.yaml` (e.g., `experimental-v1.2.3-default-gateway-report.yaml`).
+
+### Reproduce Section (within Implementation README)
+
+This section MUST exist and contain the manual or automatic steps required to reproduce the results claimed by the uploaded conformance reports for that specific implementation. If reproduction steps differ significantly between implementation versions, use sub-sections.
+
+## Report Files
+
+Conformance reports MUST be uploaded exactly as generated by the official Gateway API Inference Extension conformance test suite, without any modifications. The "Reproduce" section allows for verification of the submitted report against a fresh run.
+
+### Report Rules
+
+To be accepted, submitted conformance reports must comply with the following rules:
+
+1.  **Implementation Details:** All fields within the `implementation` block must have meaningful values:
+    * `organization`: The entity maintaining the implementation (company, open source org, individual).
+    * `project`: The name of the implementation project, unique within the organization.
+    * `url`: A valid URL for the project (e.g., GitHub repository, product page).
+    * `version`: A specific, reproducible snapshot of the implementation (e.g., tag, commit hash, release version). Branch names are not acceptable.
+    * `contact`: A list of contact points (GitHub handles like `@maintainer`, team handles like `@org/team`, email addresses, or support URLs like an issue tracker).
+2.  **Inference Extension Versioning:** The report MUST include:
+    * `gatewayAPIInferenceExtensionVersion`: The specific version of the Gateway API Inference Extension specification tested against (e.g., `v0.3.0`).
+3.  **Mode:** The `mode` field indicates the implementation's operating mode during the test run.
+4.  **Test Profile & Result:**
+    * The report MUST contain exactly one profile result under the `profiles` list for the specific conformance category being submitted (e.g., a report for "Gateway" conformance should only contain the "Gateway" profile result).
+    * The profile's `name` MUST match the conformance category (e.g., `Gateway`, `EPP`, `ModelServer`).
+    * The profile's `result` field MUST be `success`. A `success` result indicates that **all** tests defined within the Gateway API Inference Extension conformance suite for that specific profile and version passed.
+
+## Submission Process
+
+Conformance reports demonstrating a `success` result for a specific profile (e.g., `Gateway`) should be submitted via Pull Request directly to this repository (`kubernetes-sigs/gateway-api-inference-extension`).
+
+1.  Create a new folder structure under `/conformance/reports/<extension-version>/<profile-name>/` named after your implementation (e.g., `/conformance/reports/v0.3.0/Gateway/my-implementation/`).
+2.  Add your implementation's `README.md` to this folder, following the structure described above.
+3.  Add your generated conformance report YAML file(s) to this folder, ensuring they follow the naming convention `<Implementation Version>-<Mode>-<Profile>-report.yaml`.
+4.  Submit the Pull Request.
