Add option to allow custom directory for data buffering

Registered by Stuart McLaren on 2011-11-04

When adding swift large objects the data chunks are written to the default tempdir (/tmp). It would be useful to allow a custom partition/directory to be selected for the I/O buffer in order to select a partition/directory which can have different properties to /tmp, eg

* different size
* different permissions
* different filesystem/hardware type

This could potentially be called "swift_store_large_object_buffer_dir".
The S3 store seems to do something similar in terms of writing to /tmp: should an equivalent S3 option be included?
