type Storage interface {

stands for BlobStor's sub-storages

Proposed changes:

1. get rid of StorageID parameter from all ops and control identification in BlobStor scope
2. add context.Context parameter to Put / Delete (or all) methods (see peapod.Peapod)
3. use Storage.Type() as substorage ID persisted in metabase
4. ???

add context.Context parameter to Put / Delete (or all) methods (see peapod.Peapod)

Iteration methods are the first candidates IMO.
