Subject: [PATCH] tools: Add support for caching Cloud Hypervisor artefacts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Let's add support for caching Cloud Hypervisor artefacts that are
generated using the kata-deploy local-build scripts.

Right now those are not used, but we'll switch to using them very soon
as part of upcoming changes of how we build the components we test in
our CI.

Fixes: #6480
