Previously, the Cloud API endpoint `/v1/compose/{id}` return value's
`image_status.status` for a running worker job was "running", which didn't
comply with the Cloud API specification. Equivalents allowed by the API
specification are "building", "uploading" or "registering".
As a result, the Image Builder API also does not comply in this regard
to its specification, because it currently just copies the status value
string returned by osbuild-composer.
Define the `image_status.status` as a reusable type in the Cloud API
specification. This forces openapi to generate an explicit type for it,
which can be then explicitly used in the code, instead of plain strings.
Return "building", instead of "running" for running compose.
Modify api integration test to check for all valid `image_status.status`
values for a compose.
Add News entry explaining this change.
