While it might be useful for later stages in development, let's keep this simple

It's used by symfony, use API_ instead

This mainly means the keycloak config moves to a separate bundle

there is no group named "api", there is only "rest" for non-app
specific tests

The core bundle is now available on packagist

While the starter bundle gives a nice example for how to integrate an API
it makes setting up a new server harder because the user usually already
has a bundle in mind that he/she wants to add.

So remove it and instead make it easier to add bundles by improving the docs

This is now handled by the composer.json in .gitlab-ci if needed

Users shouldn't need to care about this
