Bug description:
  [Impact]
  All Ubuntu users.

  [Test case]
  Run 'sudo update-grub'. The message is shown at the beginning.

  [Regression potential]
  There is a low risk of regression given that this change is essentially a no-op; changing two environment variables that are deprecated (and have been for a long while, pre-xenial), with a single, less confusing equivalent. That said, changes to the default config options may adversely impact boot behavior for systems. Systems could start to always show the grub menu, or it may become hard to reach the menu when it was otherwise reachable due to the changes in timeout behavior. Any changes to the behavior of the boot menu timeout / default grub options should be looked at with suspicion.

  When running update-grub I am getting the following message:

  $ sudo update-grub
