Early careers framework - Maintenance mode

The repo includes a simple service unavailable page page that can be pushed to a cf app. Traffic can be rerouted to it instead of the main application. This is handy in case of a critical bug being discovered where we need to take the service offline, or in case of maintenance where we want to avoid users interacting with the service.

When enabled, all requests will receive the service unavailable page.

Upcoming Maintenance Warnings

The ECF app features an upcoming maintenance banner that can be enabled by setting the constants in app/components/banners/maintenance_component.rb.
