Bug description:
  With trusty, /bin/ping relies on having extended attributes and kernel
  capabilities to gain the cap_net_raw+p capability. This allows
  removing the suid bit.

  However, the tarball cloud images do not preserve the extended
  attributes, and thus /bin/ping does not work on a system derived from
  them.

  Summary of problem per package:
   * lxc: ubuntu cloud template needs to extract
   * download template needs to extract with xattr flags
   * server side download creation tools need xattr flags
   * [unconfirmed] tarball caches need creation and extraction with xattr flags
   * tar: need the '--xattr' and '--acl' flags backported
   * maas: uec2roottgz needs to use xattr/acl flags
   * curtin: extraction needs to use xattr/acl flags.
   * cloud-image-build: needs to create -root.tar.gz with xattr/acl flags

  Related Bugs:
   * bug 1382632: horizon insecure key file permissions
   * bug 1386237: tar strange behavior with --acl and xattr
   * bug 1313550: ping broken (xattrs lost in tar extraction)
