object-storage: final changes to remove swift diff

Final set of changes to remove the diffs carried to make UFO work with
OpenStack Swift. The code is now a complete layering on top of OpenStack Swift
where we either "monkey patch" or subclass as necessary.

See BZ 870589 (https://bugzilla.redhat.com/show_bug.cgi?id=870589).

There are a lot of changes here due for the most part to rearranging the
directory hierarchy to have create a proper python module hierarchy under the
"gluster" namespace. Plugin references have been removed. The differences that
used to be in the swift.diff file are now replaced with server implementations
for account, container, object, and proxy that subclass the swift versions.

Additionally, the plugins/conf directory has been moved to the "etc"
directory, and the plugins/bin directory promoted a level.

Unit tests pass.

A new setup.py file is provided so that the install process can use it for
creating all the necessary python install infrastructure (eggs and paste
support).

A new RPM spec file is provided which to properly install the new code, and
the sample configuration files have been modified to reference the new python
egg.
