Disable or replace autogenerated .env file

[ozywuli]

Is your feature request related to a problem? Please describe.
We use an .envrc file instead of .env for our app. But whenever storybook runs, an extra .env file is generated.

Describe the solution you'd like
Ideally, we have an option that disables the autogenerated .env.

EDIT: Turns out this .env is actually autogenerated through the ember-cli-storybook https://github.com/storybookjs/ember-cli-storybook/blob/master/index.js#L99 . Sorry about this. This can be closed.

EDIT2: you can track the issue for ember-cli-storybook here storybookjs/ember-cli-storybook#41
