Description:

This update for cloud-init fixes the following issues:
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
    ifup/ifdown accept the renderer as available.


  o Add cloud-init-break-resolv-symlink.patch (bsc#1151488) + If /etc/

    configuration location, retain Ubuntu setting [Janos Lenart] + net: skip

    (LP: #1833264) + tools/build-on-freebsd: update to python3 [GonA(C)ri Le
    Bouder] + Allow identification of OpenStack by Asset Tag [Mark T. Voelker]
    (LP: #1669875) + Fix spelling error making 'an Ubuntu' consistent. [Brian
    Murray] + run-container: centos: comment out the repo mirrorlist [Paride
    Legovini] + netplan: update netplan key mappings for gratuitous-arp (LP: #
    1827238) + freebsd: fix the name of cloudcfg VARIANT [GonA(C)ri Le Bouder] +
