[Bug 1920836] Re: Show Extended Security Maintenence status

[Chad Smith]

Another thing to note/expect: ua client in release in xenial and bionic
at the moment is a completed incompatible commandine (which we are
planning on SRUing prior to Xenial ESM, so `ua status --format=json`
will not work on something <  version 20. I'm fairly certain you
shouldn't care to support this old version of ua-tools, but you might
want to just do a pre-flight check on Xenial and bionic 'ua version' >=
20 and return (False, False) in that case notiing that those
environments should update their versionn of ubuntu-advantage-tools.

Bug description:
  [Impact]
  There is not currently a graphical method of determining if a system is subscribed to [Extended Security Maintenance](https://ubuntu.com/security/esm) updates. This is resolved by adding some [new UI](https://wiki.ubuntu.com/SoftwareUpdates#Extended_Security_Maintenance) to the software properties application.

  [Test Case]
  1. Install latest version of Ubuntu advantage:
  $ sudo add-apt-repository ppa:ua-client/stable
  $ sudo apt update
  $ sudo apt upgrade
  2. Open Software Properties
  3. Go to Updates tab.

  Expected result:
  Information is shown that indicates if this system is using Extended Security Maintenance updates, when updates will supported until, and a link to upgrade to ESM.

  Observed result:
  No ESM information currently shown.

  [Where problems could occur]
  - Software properties could hit a bug getting a response from the ua app. The current code carefully checks if and what is returned, falling back to a safe default behavior.
  - Launching software properties could trigger a bug in the ua app.
  - Software properties could show incorrect information, causing confusion for the user. The solution uses information from distro-info and the ua app which means software-properties contains no data about ESM, and instead relies on these apps that can be updated if things change.
