Users may not want to build images with a cache as it significantly slows down the build process and results in far larger images. Currently we don't depend on cache-devstack in the jenkins-slave element for this reason. Unfortunately we assume cache-devstack was run because we attempt to link to a directory created by this element. Update jenkins-slave to only make the link if the cache dir exists to address this. Users can now make cacheless images quickly and cheaply. Change-Id: I45ec2fcd614d71f1db85cab3c5c3730a96c8fd61
