Make zypper dist-upgrade opt-in on SLE/Leap (#417)

Make zypper dist-upgrade opt-in on SLE/Leap

- Create a `suse_dup` config option
- Create a new `Distribution::OpenSuseTumbleweed` object along with `upgrade_opensuse_tumbleweed()`
    * The purpose of it is to ignore the config option on Tumblweed as
      zypper `dup` is the only way to update a Tumbleweed
