Make it possible to store multiple artifacts for a build
Currently it is possible to store only one artifacts archive for given CI/CD build. Artifacts can have artifacts metadata that we consider to be an extensions of original artifacts archive file. These are however separate concepts, and we can treat artifacts metadata as a separate build artifacts.
We should create build -> has many -> artifacts association, and add artifacts type field to the database.
We need it to make a better us of CI artifacts, and to implement arbitrary build results in the future. We talked about this with @ayufan and it seems that is an important backstage improvement that we need to build many features on top of that. We also consider this to be important to solve problems of flaky tests in GitLab, see #32308.
- Make artifacts metadata a separate artifacts type.
- Make it possible to send multiple artifacts for a job using an internal runners API.
