DEV: Require Ember CLI to be used in development mode (#12738) 

We really want to encourage all developers to use Ember CLI for local
development and testing. This will display an error page if they are not
with instructions on how to start the local server.

To disable it, you can set `NO_EMBER_CLI=1` as an ENV variable
