Description

In order to better evolve the TaskExecutor component, I suggest to not make it depend on the concrete BlobServiceCache implementation. Instead I suggest to introduce a TaskExecutorBlobCacheService interface that can be implemented by the BlobServiceCache. Additionally, should make the TaskExecutor independent of the PermanentBlobCache and TransientBlobCache implementations.
