More details at the end of this text.\n<issue>\n      ### Description\n\nIn [zarf](https://github.com/defenseunicorns/zarf) we run a localhost registry on a nodeport without TLS. We have seen and had failures reported on AKS, EKS, RKE2, and k3s because `config_path` in the containerd `config.toml` is being set to a default path (that may or may not actually exist).\n\nRelevant context: https://github.com/defenseunicorns/zarf/issues/592\n\nSimilar to: https://github.com/containerd/containerd/issues/7392\n\n### Steps to reproduce the issue\n\n1. Run a k8s cluster w/ containerd\n2. Use this config\n\n```toml\n[plugins.\"io.containerd.grpc.v1.cri\".registry]\n   config_path = \"/etc/containerd/certs.d\"\n```\n3. Run an insecure, plain HTTP registry as a pod in the cluster exposed via a nodeport and push an image to it\n\n4. Run a pod that tries to pull/use an image from the in-cluster registry\n\n\n### Describe the results you received and expected\n\nExpected result: containerd sends a plain HTTP request to pull the image and it succeeds.\n\nK8s logs and the `containerd.log` file show that containerd is sending an HTTPS request rather than a plain HTTP request when trying to pull an image from the insecure localhost registry.\n\nHere's a `containerd.log` file as a result of running `zarf init` on a linux/arm64 Ubuntu VM to create a k3s cluster and bootstrap a registry in the cluster:\n\n[containerd.log](https://github.com/containerd/containerd/files/14793215/containerd.log)\n\nPrimary logs of interest:\n\n`\"host will try HTTPS first since it is configured for HTTP with a TLS configuration, consider changing host to HTTPS or removing unused TLS configuration\" host=\"127.0.0.1:30152\"`\n\nhttps://github.com/containerd/containerd/blob/b0d00f86363f825ff2d3b55e563e28d3943b5b25/core/remotes/docker/config/hosts.go#L254\n\n`\"trying next host\" error=\"failed to do request: Head \\\"https://127.0.0.1:30152/v2/library/registry/manifests/2.8.3\\\": net/http: TLS handshake timeout\" host=\"127.0.0.1:30152\"`\n\nIt appears that there is supposed to be an HTTP fallback mechanism that doesn't seem to be working as expected:\n\nhttps://github.com/containerd/containerd/blob/b0d00f86363f825ff2d3b55e563e28d3943b5b25/core/remotes/docker/config/hosts.go#L256\n\n### What version of containerd are you using?\n\n`v1.7.11`\n\n### Any other relevant information\n\nVersions affected appear to be `>=1.7.7`\n\n### Show configuration if it is related to CRI plugin.\n\n```toml\n# File generated by k3s.
