Implement the delete API by implementing soft delete for layers and blobs by removing link files and updating the blob descriptor cache. Deletion is configurable - if it is disabled API calls will return an unsupported error. We invalidate the blob descriptor cache by changing the linkedBlobStore's blobStatter to a blobDescriptorService and naming it blobAccessController. Delete() is added throughout the relevant API to support this functionality. Signed-off-by: Richard Scothern <richard.scothern@gmail.com>
