Security issue fixed:

  o CVE-2019-0816: Fixed the unnecessary extra ssh keys that were added to
    authorized_keys (bsc#1129124).

Non-security issues fixed:

  o Add cloud-init-renderer-detect.patch (bsc#1154092, bsc#1142988) + Short
    curcuit the conditional for identifying the sysconfig renderer. If we find
