The `KojiTargetResultOptions` previously contained information only
about the uploaded image file. And even then, some information, such as
the filename, were scattered in other structures such as
`KojiFinalizeJob` struct.
Since the plan is to start uploading also osbuild manifest and osbuild
build log to Koji, we need to extend the result options structure to
hold more information and also make it specific to which file is the
information related.
Rework the `KojiTargetResultOptions` to contain information about:
- the built image
- build log
- osbuild manifest
Information about each file contains:
- filename
- checksum type
- file checksum
- file size
For now, only the built image information is set and consumed by the
worker.
Add custom JSON (un)marshaler for `KojiTargetResultOptions` to handle
backward compatibility when old version of worker or composer server
interact with each other. Cover them with unit tests.
