Correct dev-quickstart installation directions

kUse was using yum to install docker 1.7.0.  This wanted to install
all of the fedora 23 dependencies.  Instead, simply use RPM to install
via http with the --nodeps option.  This works because we don't really
need selinux since we don't support an selinux operational model.
