epic: First Release Cockpit

[lfrancke]

This is an umbrella issue preparing the cockpit for the first release.

• Finalise File Browser
• Finalise Dashboard
• Open Source the project
• Documentation
• Integrating it into the SDP release cycle
• Testing

Storage Browser

There are multiple open PRs which need to be reviewed:

• Feat/s3 file browser v1 #208
• S3 File Browser v2 #289

Dashboard

• Add Proxy and dex to embed Apache Services #293

Open Source the project

• docs: rewrite README and switch licence to OSL-3.0 #204
• Decide whether we want to rewrite history or not
• Analyse/Run a cleanup of commits etc. -> to make sure we never reference customers
• Flip the switch

Documentation

I believe today we have no documentation in our main docs telling anyone about this project.
We'll need to change that.

• Include the Cockpit in our documentation

Integrating Cockpit into the SDP release cycle

Our release for each SDP version has a lot of steps and templates.
We need to make sure to include the Cockpit in this process going forward.

Testing

We need to do a lot of manual testing to see if everything is coherent.
For that, we might want to create a branch to work off and stabilise so that new features can be developed independently.
