Code Issues Proposed changes

Made Swift backing disk persistent

Browse Source 
Previously, Swift's backing disk were not be mounted after reboots,
causing swift-proxy-server service to fail with cryptic error
messages such as 'proxy-server: ERROR Insufficient Storage'. Now,
we use 	Dan Smith' create_disk function from functions to create
the backing disk for us and add it to /etc/fstab.
