Tamir Duberstein d1457acc6d ci: cache downloads

We're seeing 429 from Github trying to download gen_init_cpio, so cache
it using actions cache. Since I'm here add this for kernel images as
well to save time waiting on slow Debian servers.

Aya Integration Tests

The aya integration test suite is a set of tests to ensure that common usage behaviours work on real Linux distros

Prerequisites

You'll need:

rustup toolchain install nightly
rustup target add {aarch64,x86_64}-unknown-linux-musl
cargo install bpf-linker
libelf-dev (libelf-devel on rpm-based distros)
llvm (for llvm-objcopy)
(virtualized only) qemu

Usage

From the root of this repository:

Native

cargo xtask integration-test local

Virtualized

cargo xtask integration-test vm --cache-dir <CACHE_DIR> <KERNEL_IMAGE>...

Writing an integration test

Tests should follow these guidelines:

Rust eBPF code should live in integration-ebpf/${NAME}.rs and included in integration-ebpf/Cargo.toml and integration-test/src/lib.rs using include_bytes_aligned!.
C eBPF code should live in integration-test/bpf/${NAME}.bpf.c. It should be added to the list of files in integration-test/build.rs and the list of constants in integration-test/src/lib.rs using include_bytes_aligned!.
Tests should be added to integration-test/tests.
You may add a new module, or use an existing one.
Test functions should not return anyhow::Result<()> since this produces errors without stack traces. Prefer to panic! instead.
