Bug description:
  === Begin SRU Information ===
  [Impact]
   * When landscape-client is installed in an image (default for ubuntu cloud
     images) there is a potential race where cloud-init will update the
     /etc/landscape/client.conf after landscape-client has started.  If it
     does so, then landscape-client will not register until the next reboot.
   * The fix here is simply to restart lanscape-client after writing config

  [Test Case]
   * This is a race condition, so it will not always occur, but generally you
     can see it by launching an Ubuntu cloud image, and providing it with
     lanscape-client configuration like the user-data below, and then expecting
     that system to correctly register itself.
     #cloud-config
     apt_upgrade: True
     apt_sources:
      - source: deb $MIRROR $RELEASE-proposed main
     landscape:
       client:
         url: "https://landscape.canonical.com/message-system";
         ping_url: "http://landscape.canonical.com/ping";
         data_path: "/var/lib/landscape/client"
         http_proxy: "http://my.proxy.com/foobar";
         tags: "server,cloud"

  [Regression Potential]
   * landscape-client could not behave well when 'restart' is requested
     right after it had started.   If that was the case, this could result
     in a race where the fix didn't actually accomplish what we wanted.
   * There is very little potential for regression other than in the
     case where the user was trying to register instance with landscape.

  === End SRU Information ===

  
  After installing landscape, or otherwise configuring it, cloud-init needs to restart the service.
