drop configFileName support (replaced by configFile) BREAKING CHANGE

might be safer to save this for the next major or minor instead of patch? otherwise, seems okay.

[Hypnosphi]

We don't pass any options to it: https://github.com/storybooks/storybook/blob/master/app/angular/src/server/config/webpack.config.js#L73

[igor-dv]

We do pass here : https://github.com/storybooks/storybook/blob/master/app/angular/src/server/config.js#L23

[Hypnosphi]

Ok, but the only field is configFile which isn't deprecated https://github.com/storybooks/storybook/blob/master/app/angular/src/server/ts_config.js#L23
