If swift-recon/swift-get-nodes/swift-object-info is used with the
swiftdir option they will read rings from the given directory; however
they are still using /etc/swift/swift.conf to find the policies on the
current node.
This makes it impossible to maintain a local swift.conf copy (if you
don't have write access to /etc/swift) or check multiple clusters from
the same node.
Until now swift-recon was also not usable with storage policy aliases,
this patch fixes this as well.
