Support binary-type (package) asset for Releases

Summary

We're currently supporting the following two type of assets https://docs.gitlab.com/ee/user/project/releases/#release-assets

• Source code: state of the repo at the time of the Release
• Links: to content such as built binaries or documentation

We should support binary-type asset as well. We'll likely use GitLab Package Registry for that purpose.

Important note

• Currently, GitLab Package Registry is available on EEP, whereas GitLab Releases is Core. We might need to consider that generic binary-type of package can fall into Core as well.
