This is the most complex part to cache, as the cached component can be only used if: * There were no changes in the agent * There were no changes in the libs (used by the agent) * There were no changes in the rootfs build scripts * There is no change in the version of the following components: * attestation-agent (part of the rootfs) * gperf (used to build libseccomp) * libseccomp (used to build the agent) * pause image (part of the rootfs) * skopeo (part of the rootfs) * umoci (part of the rootfs) * rust (used to build the kata-containers and attestation agents) We're relying on the last commit merged on places related to the rootfs generation and using that as the rootfs version and that should be good enough for what we need. Apart from everything already mentioned, we've also added the ability to cache the `root_hash_vanilla.txt` and `root_hash_tdx.txt` files, as those are needed for when building the shim-v2, in order to have measured boot working there. It's important to note that we've added the ability to cache *both* files, and I've taken that path as the shim-v2 cache work (which will come soon) relies on both files.

Kata Containers packaging
Introduction
Kata Containers currently supports packages for many distributions. Tooling to aid in creating these packages are contained within this repository.
Build in a container
Kata build artifacts are available within a container image, created by a
Dockerfile. Reference DaemonSets are provided in
kata-deploy, which make installation of Kata Containers in a
running Kubernetes Cluster very straightforward.
Build a snap package
Build static binaries
See the static build documentation.
Build Kata Containers Kernel
Build QEMU
Create a Kata Containers release
See the release documentation.
Packaging scripts
See the scripts documentation.
