kernel: reworked module interface

removed boot from modules and switched to factory functions for creating modules

blob: adjusted initialization

The blob.NewStore func has been adjusted which is a breaking change.

Instead of passing a blob.Settings object, you now pass a name of the blob store. The settings are then resolved from the config from blobstore.<name>.

Furthermore the forceful prefixing of the appId.Application was removed, so that a developer can decide about the full prefix of his blob store. This is also a breaking change.

db-repo: return custom record not found error in query function

improve handling of db-repo record not found errors (#398)

Introduced a new custom record not found error that wraps the model id and record id and removed the old db_repo.RecordNotFound error.
Additionally, the apiserver crud handlers will only log a warning if this error occurs and respond with a No Content HTTP status (204).
