** Description changed:

  [Impact]
- When users are running an ESM distro and looking at motd message they may be trigger by an alert generated by update-notifier that both esm-infra and esm-apps could be enable in the machine to receive future updates. However, esm-apps will not bring much to an ESM distro. This means that
- users will be receiving alerts for esm-apps that are not necessary

  [Test case]
  
  To reproduce the issue, you can:
  
  1. Launch a xenial container
  2. create the file /etc/ubuntu-advantage/uaclient.conf with the following content:
  
  # Ubuntu-Advantage client config file.
  contract_url: 'https://contracts.canonical.com'
  security_url: 'https://ubuntu.com/security'
  data_dir: /var/lib/ubuntu-advantage
  log_level: debug
  log_file: /var/log/ubuntu-advantage.log
  features:
-   allow_beta: true
+   allow_beta: true
  
  3. install ubuntu-advantage-client from this ppa:
  https://code.launchpad.net/~ua-client/+archive/ubuntu/daily
  
  PS: Make sure to not allow the installation to override the config file
  you have just created.
  
  4. Update the version of update-notifier to the one in proposed
  5. Run `/usr/lib/update-notifier/apt-check --human-readable`
  6. Verify that both esm-infra and esm-apps alerts appear in the end of the message
  
  To verify that the error is fixed:
  
  1. Run the past scenario until step 3
  2. Install the new update-notifier from this ppa:
  https://launchpad.net/~lamoura/+archive/ubuntu/update-notifier-test-ppa/
  3. Run `/usr/lib/update-notifier/apt-check --human-readable`
  4. Verify that only esm-infra is now showing an alert message at the end
  
  [Where problems could occur]
  
  We are only changing here the condition to output esm-apps alerts. If that condition is not right we may miss to display those messages to users that
  need them.
  
  [Discussion]
  When running /usr/lib/update-notifier/apt-check on a ESM machine, we could alert the user about the existence of both esm-infra and esm-apps if the system has unauthenticated source file for both services. Therefore, we would display a message like that in the system:
  
  --------------------------
  Enable UA Apps: ESM to receive additional future security updates.
  See https://ubuntu.com/security/esm or run: sudo ua status
  
  Enable UA Infra: ESM to receive additional future security updates.
  See https://ubuntu.com/security/esm or run: sudo ua status
  ----------------------------------
  
  This is not ideal, since ESM machine will not gain much from esm-apps.
  Also, this messaging may hide the importance of using esm-infra on ESM
  machines, since the users will not know beforehand which service to
  prioritize.
