Flatpak Integration in Packages
<!-- ===> To everyone reading this in the Markdown version
I've commented out the parts of the template that I didn't answer.
I'm not sure whether you actually need them as they seem kinda overkill, but feel very
free to uncomment them if you want to add details.
I didn't want to remove them as it seems like a lot of work to copy them over again

<!-- The first three sections: "Problem to solve", "Intended users" and "Proposal", are strongly recommended, while the rest of the sections can be filled out during the problem validation or breakdown phase. However, keep in mind that providing complete and relevant information early helps our product team validate the problem and start working on a solution. -->
### Problem to solve
<!-- What problem do we solve? Try to define the who/what/why of the opportunity as a user story. For example, "As a (who), I want (what), so I can (why/value)." -->
[Flatpak][flatpak], like SNAP, is a rather new way for GNU/Linux developers to distribute packaged binary releases of their applications across Unix-like systems without having to rely on the users' libraries. With Flatpak it is generally easier for developers to track down errors and to distribute new versions.
As a software developer for GNU/Linux, I'd like to be able to deploy my Flatpak apps directly using GitLab. Currently, we use Artefacts to provide exported bundles and a custom script to export the software to our Flatpak repository.
I think this might be related to the already existent Packages feature. Flatpak allows you to deploy multiple versions of your software to a single repository, so "Packages" in my opinion is the best place to put a feature like this.
Given that the GNU/Linux software community using Flatpak mostly consists of Free Software project, I'd love to see this feature available in the Free Software CE version of GitLab. However, proprietary projects might find this feature useful as well.
### Intended users
<!-- Who will use this feature? If known, include any of the following: types of users (e.g. Developer), personas, or specific company roles (e.g. Release Manager). It's okay to write "Unknown" and fill this field in later.

### Further details
<!-- Include use cases, benefits, goals, or any other details that will help us understand the problem better. -->
The GNOME project currently uses a [rather complicated CI configuration][gnome-ci] to automatically deploy their apps to their [nightly repository][gnome-nightly].
Moreover, the Flatpak developer help has a section on [Hosting a repository][flatpak-hosting].
### Proposal
<!-- How are we going to solve the problem? Try to include the user journey! https://about.gitlab.com/handbook/journeys/#user-journey -->
This problem could be solved by adding a "Flatpak Repository" feature in the "Packages" category.
### Permissions and Security
<!-- What permissions are required to perform the described actions? Are they consistent with the existing permissions as documented for users, groups, and projects as appropriate? Is the proposed behaviour consistent between the UI, API, and other access methods (e.g. email replies)?-->
Access level requirement should be somehow linked to creating releases. However, there should always be a (simple) way for the CI to deploy Nightlies.
<!--### Documentation
<!-- See the Feature Change Documentation Workflow https://docs.gitlab.com/ee/development/documentation/feature-change-workflow.html
* Add all known Documentation Requirements in this section. See https://docs.gitlab.com/ee/development/documentation/feature-change-workflow.html#documentation-requirements
* If this feature requires changing permissions, update the permissions document. See https://docs.gitlab.com/ee/user/permissions.html -->
<!--### Availability & Testing
<!-- This section needs to be retained and filled in during the workflow planning breakdown phase of this feature proposal, if not earlier.
What risks does this change pose to our availability? How might it affect the quality of the product? What additional test coverage or changes to tests will be needed? Will it require cross-browser testing?
Please list the test areas (unit, integration and end-to-end) that needs to be added or updated to ensure that this feature will work as intended. Please use the list below as guidance.
* Unit test changes
* Integration test changes
* End-to-end test change

<!--### What does success look like, and how can we measure that?
<!-- Define both the success metrics and acceptance criteria. Note that success metrics indicate the desired business outcomes, while acceptance criteria indicate when the solution is working correctly. If there is no way to measure success, link to an issue that will implement a way to measure this. -->
<!--### What is the type of buyer?
<!-- What is the buyer persona for this feature? See https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/buyer-persona/
In which enterprise tier should this feature go? See https://about.gitlab.com/handbook/product/pricing/#four-tiers -->
<!--### Is this a cross-stage feature?
<!-- Communicate if this change will affect multiple Stage Groups or product areas. We recommend always start with the assumption that a feature request will have an impact into another Group. Loop in the most relevant PM and Product Designer from that Group to provide strategic support to help align the Group's broader plan and vision, as well as to avoid UX and technical debt. https://about.gitlab.com/handbook/product/#cross-stage-features -->
