Remove all the internal package that are now in the
github.com/osbuild/images package and vendor it.
A new function in internal/blueprint/ converts from an osbuild-composer
blueprint to an images blueprint. This is necessary for keeping the
blueprint implementation in both packages. In the future, the images
package will change the blueprint (and most likely rename it) and it
will only be part of the osbuild-composer internals and interface. The
Convert() function will be responsible for converting the blueprint into
the new configuration object.
Instead of having an extra field, `TlsVerify`, on the `Client` and
then later setting the corresponding `SystemContext` options, use
the existing `SystemContext` field of `Client`. The corresponding
field is a tri-state: unset, true, false, which is represented as
a pointer to boolean in the `Client`'s new getter and setter. This
also inverts the boolean logic from verify TLS to skip TLS which
aligns very well with the corresponding fields in the upload target
struct.
In addition we properly capitalize some existing variables.
Add a new generic container registry client via a new `container`
package. Use this to create a command line utility as well as a
new upload target for container registries.
The code uses the github.com/containers/* project and packages to
interact with container registires that is also used by skopeo,
podman et al. One if the dependencies is `proglottis/gpgme` that
is using cgo to bind libgpgme, so we have to add the corresponding
devel package to the BuildRequires as well as installing it on CI.
Checks will follow later via an integration test.
