The "Capability" type defines DataScope and ConnectivityScope fields, but their value was set from consts in the datastore package, which required importing that package and its dependencies for the consts only. This patch: - Moves the consts to a separate "scope" package - Adds aliases for the consts in the datastore package. Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
