Minor: k3s update from v1.27.3+k3s1 to v1.27.5+k3s1

[cguertin14]

This release updates Kubernetes to v1.27.5, and fixes a number of issues.

For more details on what's new, see the Kubernetes release notes.

Changes since v1.27.4+k3s1:

• Update cni plugins version to v1.3.0 (#8056)
  • Upgraded cni-plugins to v1.3.0
• Update flannel to v0.22.1 (#8057)
  • Update flannel to v0.22.1
• ADR on secrets encryption v3 (#7938)
• Unit test for MustFindString (#8013)
• Add support for using base template in etc/containerd/config.toml.tmpl (#7991)
  • User-provided containerd config templates may now use {{ template "base" . }} to include the default K3s template content. This makes it easier to maintain user configuration if the only need is to add additional sections to the file.
• Make apiserver egress args conditional on egress-selector-mode (#7972)
  • K3s no longer enables the apiserver's enable-aggregator-routing flag when the egress proxy is not being used to route connections to in-cluster endpoints.
• Security bump to docker/distribution (#8047)
• Fix coreos multiple installs (#8083)
• Update stable channel to v1.27.4+k3s1 (#8067)
• Fix tailscale bug with ip modes (#8077)
• Consolidate CopyFile functions (#8079)
• E2E: Support GOCOVER for more tests + fixes (#8080)
• Fix typo in terraform/README.md (#8090)
• Add FilterCN function to prevent SAN Stuffing (#8085)
  • K3s's external apiserver listener now declines to add to its certificate any subject names not associated with the kubernetes apiserver service, server nodes, or values of the --tls-san option. This prevents the certificate's SAN list from being filled with unwanted entries.
• Bump docker/docker to master commit; cri-dockerd to 0.3.4 (#8092)
  • Bump docker/docker module version to fix issues with cri-dockerd caused by recent releases of golang rejecting invalid host headers sent by the docker client.
• Bump versions for etcd, containerd, runc (#8109)
  • Updated the embedded containerd to v1.7.3+k3s1
  • Updated the embedded runc to v1.1.8
  • Updated the embedded etcd to v3.5.9+k3s1
• Etcd snapshots retention when node name changes (#8099)
• Bump kine to v0.10.2 (#8125)
  • Updated kine to v0.10.2
• Remove terraform package (#8136)
• Fix etcd-snapshot delete when etcd-s3 is true (#8110)
• Add --disable-cloud-controller and --disable-kube-proxy test (#8018)
• Use go list -m instead of grep to look up versions (#8138)
• Use VERSION_K8S in tests instead of grep go.mod (#8147)
• Fix for Kubeflag Integration test (#8154)
• Fix for cluster-reset backup from s3 when etcd snapshots are disabled (#8155)
• Run integration test CI in parallel (#8156)
• Bump Trivy version (#8150)
• Bump Trivy version (#8178)
• Fixed the etcd retention to delete orphaned snapshots based on the date (#8177)
• Bump dynamiclistener (#8193)
  • Bumped dynamiclistener to address an issue that could cause the apiserver/supervisor listener on 6443 to stop serving requests on etcd-only nodes.
  • The K3s external apiserver/supervisor listener on 6443 now sends a complete certificate chain in the TLS handshake.
• Bump helm-controller/klipper-helm versions (#8204)
  • The version of helm used by the bundled helm controller's job image has been updated to v3.12.3
• E2E: Add test for k3s token (#8184)
• Move flannel to 0.22.2 (#8219)
  • Move flannel to v0.22.2
• Add new CLI flag to enable TLS SAN CN filtering (#8257)
  • Added a new --tls-san-security option. This flag defaults to false, but can be set to true to disable automatically adding SANs to the server's TLS certificate to satisfy any hostname requested by a client.
• Add RWMutex to address controller (#8273)
• Update to v1.27.5 (#8236)
