In dotnet we throw this and provide more data than just message.

Confirmed with @xiafu-msft and we are now throwing ResourceModifiedError as per blob natively does in this case.

Blobs:
Currently in blobs we lock on etag, and we try to let the user override this by passing

Added locking on etag - previously there was no etag locking.
