Add crictl events command

[surik]

What type of PR is this?

/kind feature

What this PR does / why we need it:

This pull request introduces the crictl events command, designed to consume events. It comes in response to the recent developments in both cri-o (since version 1.26) and containerd (since version 1.7), both of which have integrated endpoints for streaming Evented PLEG. Notably, containerd currently lacks multi-subscriber support which I'm trying to address in containerd/containerd#8916.

Which issue(s) this PR fixes:

None

Special notes for your reviewer:

Does this PR introduce a user-facing change?
