Bug description:
  [Impact]
  There is an update on how the ESM services are named on the Ubuntu Advantage Client (UA) project.
  We need to change those names on update-notifier as well to provide an unified user experience regarding the ESM services.

  We are changing:

  UA Infra: ESM -> ESM Infra
  UA Apps: ESM -> ESM Apps
  UA Infra: Extended Security Maintenance (ESM) ->  Expanded Security Maintenance for Infrastructure
  UA Apps: Extended Security Maintenance (ESM) ->  Expanded Security Maintenance for Applications

  [Test Case]
  To test this change, use the following script:

  ---------------------------------------------
  #!/bin/bash
  set -e

  series=$1
  token=$2
  name=$series-dev

  function cleanup {
    lxc delete $name --force
  }

  function on_err {
    echo -e "Test Failed"
    cleanup
    exit 1
  }

  trap on_err ERR

  lxc launch ubuntu-daily:$series $name
  sleep 10

  # Update update-notifier package
  lxc exec $name -- sh -c "echo \"deb http://archive.ubuntu.com/ubuntu $series-proposed main\" | tee /etc/apt/sources.list.d/proposed.list"
  lxc exec $name -- sudo apt-get update > /dev/null
  lxc exec $name -- sudo apt-get install update-notifier-common -y > /dev/null
  lxc exec $name -- apt-cache policy update-notifier-common

  # Running update-motd for machine without an ua subscription
  echo -e "\n* Updated update-notifier message"
  echo "###########################################"
  lxc exec $name -- /usr/lib/update-notifier/apt-check --human-readable
  echo -e "###########################################\n"

  # Attaching machine to a UA subscription
  echo "Attaching to a UA subscription"
  lxc exec $name --  ua attach $token > /dev/null
  lxc exec $name --  ua status

  # Running update-motd for attached machine
  echo -e "\n* Updated update-notifier message with system attached to UA"
  echo -e "###########################################"
  lxc exec $name -- /usr/lib/update-notifier/apt-check --human-readable
  echo -e "###########################################\n"

  # Installing all esm-infra packages
  lxc exec $name -- sudo apt-get upgrade -y > /dev/null

  # Disabling esm-infra
  lxc exec $name -- sudo pro disable esm-infra --assume-yes > /dev/null

  echo "* Updated update-notifier message with esm-infra disabled"
  echo "###########################################"
  lxc exec $name -- /usr/lib/update-notifier/apt-check --human-readable
  echo -e "###########################################\n"

  cleanup
  -----------------------------------------------------

  Notice that you need a UA token to run this script.
  Additionally, most messages will appear on the xenial machine due to it being ESM already

  [Regression Potential]
  See translatable string note in comment 3.

  We are just providing message changes, so the regression potential is
  really low. User might notice the changes, but they are not that
  different from the original ones.
