Change the default container runtime CRI socket endpoint to the
one of containerd. Previously it was the one for Docker
- Rename constants.DefaultDockerCRISocket to DefaultCRISocket
- Make the constants files include the endpoints for all supported
container runtimes for Unix/Windows.
- Update unit tests related to docker runtime testing.
- In kubelet/flags.go hardcode the legacy docker socket as a check
to allow kubeadm 1.24 to run against kubelet 1.23 if the user
explicitly sets the criSocket field to "npipe:////./pipe/dockershim"
on Windows or "unix:///var/run/dockershim.sock" on Linux.
- Update defaults for v1beta2 and 3 to have URL scheme
- Raname DefaultUrlScheme to DefaultContainerRuntimeURLScheme
- Prepend a missing URL scheme to user sockets and warn them
that this might not be supported in the future
- Update socket validation to exclude IsAbs() testing
(This is broken on Windows). Assume the path is not empty and has
URL scheme at this point (validation happens after defaulting).
- Use net.Dial to open Unix sockets
- Update all related unit tests
