Bug description:
  [Impact]
  This release sports both bug-fixes and new features and we would like to
  make sure all of our supported customers have access to these
  improvements. The notable ones are:

    * add support for realtime kernel service on Jammy as a beta service
    * update code to use new contract overrides directive
    * Make FIPS an incompatible service for FIPS Updates
    * Unhold more FIPS packages when enabling FIPS
    * Unhold FIPS packages when enabling FIPS Updates

  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.

  [Regression Potential]
  Since we using a new contracts directive to perform series and cloud specific overrides on the entitlements definitions, we could be parsing that information incorrectly, not respecting the
  overrides. We have an extensive number of tests to cover different scenarios for services enablement/disablement to verify is this is not happening, but it can still be a problem.

  We are also adding a new service that can only be enabled on Jammy.
  This service is incompatible with Livepatch, FIPS and FIPS Updates. If
  we have made any mistake on that implementation, we could have a gap
  where users will be able to enable it on other series or together with
  the incompatible services, but we do have tests that cover that.

  [Discussion]
  Most of the FIPS work on this release is aimed at allowing FIPS PRO machines to enable FIPS Updates if necessary. On those machines, the FIPS packages are installed and hold during the image creation. When UA runs auto-attach on the first boot, we enable FIPS and unhold those packages. However, we have identified that we were not unholding all of the FIPS packages anymore. This means that if an user tries to enable FIPS Updates, it will fail because we will not be able to install some of the FIPS Updates packages due to some package holds. Besides fixing that, we have also added safer mechanisms here to guarantee that we will properly unhold all the packages, like unholding them when FIPS Updates is being enabled.

  [Changelog]

    * New upstream release 27.8 
      - entitlements: apply overrides from the contract response
      - fips:
        + unhold fips package when enabling fips-updates
        + make fips service incompatible with fips-updates
        + unhold more packages when enabling fips 
      - lib: fix upgrade script for unsupported releases
      - realtime: add suport for realtime kernel beta service on Jammy
