Peter Portante dad04a8739 object-storage: use temp file optimization for pkl
Override OpenStack Swift's swift.common.utils.write_pickle with our own
implementation that uses the GlusterFS temporary file operation. A file name
'.<FILENAME>.<RANDOM>' will hash to the same GlusterFS node as a file named
'<FILENAME>', those avoiding a move of the file on a rename.

This is part of the work needed to address BZ 876660
(https://bugzilla.redhat.com/show_bug.cgi?id=876660).
