Bug description:
  [Impact]
  This is for the release of the latest upstream version of the Ubuntu Pro Client, which contains several bugfixes and new features that are desirable on all releases.

  The most notable changes are:
   - certain user settings are moving out of uaclient.conf to a
     non-conffile intended to be managed by the pro config subcommand
   - a new api function for querying the status of unattended-upgrades
   - a clean-up of how we add messages to motd
   - a clean-up of our apt integration for showing esm updates
   - show warnings when a livepatch is enabled on an unsupported kernel
   - our log format has changed to jsonlines
   - instead of a network request to the contract server during every
     "pro status", we now check with the contract server for updates
     every 24 hours (only if attached)

  See the changelog entry below for a full list of changes and bugs.

  [Test Case]
  The following development and SRU process was followed:
  https://wiki.ubuntu.com/UbuntuAdvantageToolsUpdates

  The ubuntu-advantage-tools team will be in charge of attaching the
  artifacts and console output of the appropriate run to the bug.
  ubuntu-advantage-tools team members will not mark ‘verification-done’
  until this has happened.

  There will be additional tests for the conffile migration change to
  ensure it isn't disruptive during upgrades in common scenarios. These
  are defined in a script in the source upload "sru/release-27.14"
  directory.

  [Regression Potential]
  This release includes some refactors of existing functionality, such as our notice system for displaying various messages in `pro status` output, as well as our separate system for displaying messages in MOTD. If there are bugs in these refactors, then certain messages may not get displayed to the users. These messages are mostly about contract expiration dates for MOTD, and can include some reboot notices or other service-state related situations for pro status notices.

  There are many changes to the packaging scripts. If there are mistakes
  here, then they could error during an apt upgrade, in scenarios not
  considered in testing.

  The migration of some settings out of uaclient.conf could fail in
  certain situations and result in an un-migrated conffile that would
  need user-action to fix. Also, if there are mistakes in the migration
  code, then user-defined settings may not be respected after the
  upgrade.

  This release changes the format of our log file. If other software was
  relying on the previous structure, then it will break.

  We remove the lru_cache from the functions that create the apt Cache objects in the code. This change may affect the performance of any command which runs apt.Cache more than once. However:
  - We see no significative change in performance in commands which use it today (fix, security-status) because those only call each function once
  - There is no way to work around this, as the Cache must always be read right before used, and older instances become stale if configuration or content changes.

  More generally, there are several new features and lots of code
  changed. We could have inadvertently introduced new failure cases in
  any of this.

  [Discussion]
  This includes a large amount of fixes and features. Please take your time reviewing and ask the pro team questions. We'd like to get this released before it gets too close to Lunar launch time.

  We also have a 27.14.1 planned which will include one commit and if
  all goes well, we would like it to supersede 27.14 in -proposed before
  it gets released to -updates. We don't think this should hold-up
  review of the rest of 27.14.
