ci: Use ccache in CI and manual workflows#464
Merged

Conversation
Ccache is now active for both aklite-dev and aklite-dev-e2e images, so we can use it in CI and manual workflows to speed up builds. Each image has a different cache key. The key also contains the git commit hash, to allow updates to the cache when the code changes. If the specific hash is not found, the cache will be restored using the latest cache. Two new jobs where added to refresh the cache for both images, and are set as dependencies for the other jobs. This avoids multiple jobs having to perform the same compilation in parallel. When using ccache effectively, the current CI workflow time is reduced from about 22.5 minutes to about 19.5 minutes. Additional reduction is expected once we split the jobs further, which makes more sense now that each job does not need to perform the same compilation.
