CP/DP Split: remove unneeded provisioner mode

With the new deployment model, the provisioner mode for conformance tests is no longer needed. This code is removed, and at a later date the conformance tests will be updated to work with the new model.

Also removed some unneeded metrics collection.

@@ -44,9 +44,8 @@ To create a new release, follow these steps:
    1. Kick off the [longevity tests](https://github.com/nginx/nginx-gateway-fabric/blob/main/tests/README.md#longevity-testing) for both OSS and Plus. You'll need to create two clusters and VMs for this. Before running, update your `vars.env` file with the proper image tag and prefixes. NGF and nginx images will be available from `ghcr.io`, and nginx plus will be available in GCP (`us-docker.pkg.dev/<GCP_PROJECT_ID>/nginx-gateway-fabric/nginx-plus`). These tests need to run for 4 days before releasing. The results should be committed to the main branch and then cherry-picked to the release branch.
    2. Kick off the [NFR workflow](https://github.com/nginx/nginx-gateway-fabric/actions/workflows/nfr.yml) in the browser. For `image_tag`, use `release-X.X-rc`, and for `version`, use the upcoming `X.Y.Z` NGF version. Run the workflow on the new release branch. This will run all of the NFR tests which are automated and open a PR with the results files when it is complete. Review this PR and make any necessary changes before merging. Once merged, be sure to cherry-pick the commit to the main branch as well (the original PR targets the release branch).
 5. Run the [Release PR](https://github.com/nginx/nginx-gateway-fabric/actions/workflows/release-pr.yml) workflow to update the repo files for the release. Then there are a few manual steps to complete:
-   1. Update the version tag used in the [provisioner manifest](/tests/conformance/provisioner/provisioner.yaml) and [getting started guide](/site/content/get-started.md).
-   2. Update the [README](/README.md) to include information about the release.
-   3. Update the [changelog](/CHANGELOG.md). There is going to be a new blank section generated by the automation that needs to be adjusted accordingly.
