This commit adds a new testutil.MockCommand() helper that will
mock a command in $PATH to allow easier testing of e.g. the
`image-builder-cli build` comamnd that will invoke osbuild.
This commit provides a `blueprintload` package that can be used
to load blueprints from json/toml from a path. This will be used
in `bootc-image-builder` and `image-builder-cli` and should
eventually be merged into `images`.
This commit adds a new generic `manifestgen` package that can be
used to generate osbuild manifests. It works on a higher level
then the low-level `manifest` package from `images` and provides
plugable resolvers and a streamlined API.
This package is meant to be moved to the `images` library eventually.
