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).
