Subject: [PATCH] ping/rust: introduce rust cross-version test (#26)

* ping/go: fix composition name

* ping/rust: introduce the ping/rust test

* Showcase version selection through features

Can be run with `cargo check --features libp2pv0450` or `cargo check --features
libp2pv0440`.

* Peer programming session

* ping/rust: experiment with master & current groups

* ping/rust/src/main: Simplify import across versions

* ping/rust/src/main: Remove commented out code

* ping/rust/src/main: Clean up

* ping/rust/Dockerfile: Update crates.io index in separate step

Potentially allows caching.

* ping/rust/Dockerfile: Don't both build and install

Building the binary in release mode is enough.

* ping/rust/src/main: Clean up log lines

* ping/rust: Implement iterations with latency

* ping/rust/src/main: Extract signal and wait logic into fn

* ping/rust/Dockerfile: import caching fixes

* ping/: add cross-version composition

* ping/rust: add json payloads fix

* ping/rust: match iterations id with go

* ping/rust/Dockerfile: improve caching

* ci: introduce workflow ping-interop-rust

* ping/interop: update latest versions

* ping/_compositions: add full ping interop

* ci: resolve git reference to sha

* ping/rust/Dockerfile: drop cargo output

* ping/rust: drop version indirection

* ping/rust/Dockerfile: fix features to support caching

* ping/rust/Dockerfile: do not cache the rewritten package

* ping/_compositions/*: use concurrent_builds

* ping/_compositions/*: drop test_instances count

* ci: build composition then run

* ping: introduce InteropTarget option

* ci: fix interop target & build

* ping/_compositions/*: introduce load_resource

* ci: 10 minutes timeout for the run step

* README: add update instruction for rust & clean go

* ping/rust/Dockerfile: add protocol buffer compiler

* ping/rust/Cargo.lock: cargo update packages

* .github: increase testground timeout
