New core repository (#6950)

This PR introduces the following major changes:

    remove old middleware (nuxt-based) package and copy https://github.com/vuestorefront/middleware in its place (vuestorefront/middleware repo should be archived in the future)
    copy https://github.com/vuestorefront/sdk to the repo (sdk repo should be archived)
    remove all other packages except packages/cli (the removed packages are backed up on the legacy branch due to support reasons)

Minor/secondary changes:

    start using unified ci/cd for all packages; align containing code with the integrations team eslint config etc.
    setup sonarcloud for all 3 packages
