I was using older versions of the Ubuntu packages
that shipped with broken upstart scripts.
I am removing these patches now that I am using packages
that work.
Also updates the spec tests to account for the changes.
This commit adds support for fedora.
It introduces a params namespace class
to hold data differences between ubuntu and fedora.
It also moves the xfs packages into their own class (swift::xfs)
It is possible that the memcache server(s) may
reside on different machines than the swift
proxy.
This commit decouples the configurations of the
two services.
