StorageException should include information on relevant entities
When operating on tables and blobs and something goes wrong, Azure throws a `StorageException`.
`.RequestInformation.ExtendedErrorInformation` will give you a bit of information about what went wrong, such as this when trying to insert a duplicate key into a table:
`The specified entity already exists`
But it doesn't tell you *which* entities the failure relates to. It would be useful for StorageException to include the Partition Key and Row Key of related entities.
