Remove "ufo" directory, promoting contents to top-level

Additionally, we drop the "ufo" references from setup.py, spec file
and README, and add the HISTORY file describing how the repo was
initially created. We also update the RPM spec file to use the name
"gluster-for-swift" to avoid colliding with existing RPM names from
RHS 2.0 (the spec file's description was also updated, along with
the version number).
