Allow Policies to defer updates
The OmahaResponseHandlerAction consults with the Policy to confirm if
the generated InstallPlan can be actioned or not. If not, then the
UpdateAttempter reports to Omaha that the update has been deferred and
reverts to a status of IDLE.
This causes an API-visible transition through REPORTING_ERROR, before
ending at IDLE.
