Title:
  Reset state after a Cancel

Status in Ubuntu system image (server/client/updater):
  Invalid
Status in “system-image” package in Ubuntu:
  Invalid

Bug description:
  Currently, after a Cancel, the dbus daemon has to be .Exit()'d before
  it can be used again.  This is because of the state that the daemon
  carries, and the fact that it's not yet possible to reset the state.

  This isn't very convenient for the u/i although with dbus activation,
  it's workable.  Better would be to automatically (or explicitly?)
  reset the state after a Cancel so that the u/i could do this:

  CheckForUpdates() -> True
  Cancel() -> Canceled
  CheckForUpdates() -> True
  GetUpdates() -> ReadyToReboot

  Resetting the state would also allow for this:

  CheckForUpdate() -> False
  (wait a little while)
  CheckForUpdate() -> True
