Traits for resolving Move modules and resources from persistent storage A persistent storage backend that can resolve modules by address + name. Storage backends should return

• Ok(Some(..)) if the data exists
• Ok(None) if the data does not exist
• Err(..) only when something really wrong happens, for example - invariants are broken and observable from the storage side (this is not currently possible as ModuleId and StructTag are always structurally valid) - storage encounters internal error
