v0.8.0

Added

• Auto-registration mode: the middleware registers itself when loaded as a CAP plugin
• Declarative configuration through package.json / cds-rc.json
• Programmatic registration is still possible, but disables auto mode then

Changed

• Make dependency to @sap/cds-dk optional. If running with the cds executable during development, the dependency is fulfilled anyways. Only when running as part of a deployed app with cds-serve, then such a dependency is needed.
