Changes

• Adding the new integrated end device onboarding flow
  • Adding devices using the device repository
  • Adding devices manually
  • Claiming devices using the device repository
  • Claiming devices providing device type information manually
  • Scanning end device QR codes to provide device information
  • Choosing the right provisioning type (registration or claiming) based on the Join EUI
• Adding and extending cypress end-to-end tests for device onboarding
• Various related adjustments to other components

Testing

There was a lot of testing involved in this both manually and using end-to-end test specifications

Regressions

This PR also removes the old device onboarding flow, but still integrates a lot of that former logic. We tried our best to test any possible flow but a change of this size is not unlikely to have some regressions. These regressions should be related to whether certain devices can be registered and/or how the registration will be fulfilled on the individual stack components.

Notes for Reviewers

In detail review should not be possible, since this PR only combines parts that have already been reviewed. I have not changed anything with regards to implementation, only reorganized commits, did some file renaming and added a changelog entry.

Please still do a small review to double-check whether there is anything odd.
