node-installer: support containerd 2.0

[vdice]

Some distributions of Kubernetes ship with containerd 2.0 which uses a new config file schema; see https://github.com/containerd/containerd/blob/release/2.0/docs/cri/config.md.

One such example is k3d/k3s, using images starting with v1.32.2+k3s1.

We'll need to update node-installer to support containerd 2.0. I'm assuming in addition to its current containerd 1.x support?

I'm assuming in addition to its current containerd 1.x support?

To ensure a high level of compatibility, I'd appreciate support for both versions of containerd.
