DEV: Use Ember CLI middleware to decorate the index template (#12292)
* DEV: Use Ember CLI middleware to decorate the index template

Previously we'd do this on the client side which did not support our
full plugin API. Now requests for the index template will contact the
dev server for a bootstrap.json and apply it to the current template.

* FIX: Allows logins in development mode for Ember CLI
