• Make the wizard be displayed on first launch
• Implement Create Admin User step

• Implement Edge component step (reuse components from Adding Edge in Core using a wizard #1821)
• Implement edge component adaptation step (reuse components from Adding Edge in Core using a wizard #1821)
• Implement confirmation step
• Use values configured in the general configuration step in favor of env variables
• Set default expiry time for certificates/ca for several years
• Handle detecting that an old instance with already existing data is used (skip wizard?) - [Epic] Migration to 2.0 wizard #1894

Todo:

• Certificate upload scenario (for v2.0.0) - Own certificate upload during initial setup wizard #1976
• Decide at what point should the user login. (alpha) - Auto login user during initial setup wizard #1977
• Add transition between the wizard finish and location setup (alpha) - Add transition between the initial wizard finish and location setup #1978
• Implement way of skipping steps. If the given step is already finished, we should skip that step on the next wizard run (the app may crash/disconnect when wizard is open, so the progress should be probably persisted across restarts) (v2.0.0) - Persist initial wizard setup state between core restarts #1979
• Adjust e2e tests to the new wizard (v2.0.0) - Adjust e2e tests to the new initial wizard #1980
