[FFe] ubuntu-advantage-tools 27.14

[Grant Orndorff]

ubuntu-advantage-tools 27.14 includes several features and bug fixes to support customer requests and make the `pro` tool more usable. The most notable features 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)

The full changelog can be found at the bottom of this description. Note that we don't have an "upstream" changelog - debian/changelog is the only changelog we maintain since u-a-t is an ubuntu-only application.

All new ubuntu-advantage-tools versions including all features are SRU'd back to all supported releases including xenial. As part of this process, ubuntu-advantage-tools goes through extensive integration testing. We will attach the lunar-specific test results to this bug.

We're sorry - this FFE is later in the process than we'd like.

We hope to adopt a more regular release schedule in the near future to avoid last minute exceptions like these going forward.
