Bug description:
  [Impact]
  This is a new upstream release that addresses various issues present in 2.2 and introduces various features that improve the robustness, and feature set of MAAS.

  MAAS 2.3.0 introduces the following features:

      - Add support for CentOS & Windows networking.
      - Add support for Upstream Proxy.
      - Add the ability to deploy rack controllers.
      - Add the ability to report controller versions.
      - Add HTTP boot for ephemeral images, instead of 'tgt'.
      - Add django 1.11 support.
      - Introduce beaconing for better network discovery.
      - Improve hardware testing for better usage and feedback.
      - Improves performance by improving DNS reloading performance.
      - Machine, devices & controller page re-design.

  [Test Case]
  MAAS testing has been done in various cases, partially documented https://wiki.ubuntu.com/MAASUpdates. This include:

  1. Manual Fresh installation of MAAS
  2. Manual upgrade from the previous Ubuntu Release.
  3. Automated (CI) testing of MAAS install and operation as per the MAAS' CI.
  4. Automated (CI) testing of MAAS install and operation against other Canonical's product (juju, Canonical OpenStack & Kubernetes) provided by the Canonical Solutions QA Team.
  5. Manual split region/rack test are performed. This is to ensure that if we upgrade a MAAS Region to a newer version, the MAAS rack of the older version remains connected and operational.

  All of this includes verifying normal operation, issues fixed, and
  ensuring that Canonical Cloud solutions can inter-operate. MAAS
  releases are also now vetted by the Solutions QA team.

  [Regression Potential]
  Minimal (For MAAS itself). MAAS is fully backwards compatible and handles upgrades from previous releases which result in the continuous operation of MAAS. Users will continue to use this new version of MAAS as they used it before.

  Medium (For not tested set of hardware) - A new version of Curtin has
  been SRU'd, and as such, this could impact the deployment of untested
  hardware Paths. MAAS, in itself, has not changed the way it deploys
  machines, but curtin (the one in charge of network, disk & boot-order)
  has.
