[FFe] ubuntu-advantage-tools 27.7

[Grant Orndorff]

ubuntu-advantage-tools 27.7 includes several features and bug fixes to support customer requests and make the `ua` tool more usable. The most notable features are:

  * --format=json for attach,detach,enable,disable
  * --attach-config option when attaching for users to pass their token via a file and also to customize the auto-enabled services
  * Support enabling FIPS and FIPS-Updates on containers
  * Add more information to `ua security-status` and remove --beta flag
  * New log files will be world readable

The full changelog can be found at the bottom of this description

The json output features support the ua-integration work that is ongoing for Desktop Ubuntu Pro and subiquity.

The attach and fips changes allow customers to use `ua` in docker in a reasonable manner.

The security-status changes make the command more useful for presenting potential UA related updates to the user and is needed for Desktop Ubuntu Pro.

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 jammy-specific test results to this bug.

Attaching the jammy integration test results for ua 27.7.

[Łukasz Zemczak (sil2100)]

Ok, this feels a bit late, but since we basically never stick with one 'stable' version of UA across the board (and this being always a moving target for all series), I think this should be fine. I approve of this FFe but only if the 27.7 version lands in jammy before the Beta freeze. Please proceed.

[Grant Orndorff (orndorffgrant)]

Thank you Lukasz! Yes, we understand this timing is unideal. We'll try to avoid such a late release in the future. We will certainly land this before Beta freeze.
