Rename shim-client to shim-proto

[mxpv]

You mean directory name or crate name?
Crate itself named containerd-shim-client (I used containerd- prefix everywhere for clarity that this is relevant for containerd).
I don't mind having containerd-shim-proto, the only cons I see is that this crate is already published on crates.io, so renaming might be a bit confusing to users which one is correct to use.

I mean to rename the crate name. It's great to share "containerd-" prefix for all crates from the rust-extensions project. I prefer "containerd-shim-proto" over "containerd-shim-client" because

1. it's a library instead of a binary
2. it contains code for both server and client.

But it's true that it may cause some confusions:(

Seems cargo yank may help here:
