Desired functionality

I'd like --lint-fix flag for ng generate to support tslint.yaml configuration in addition to tslint.json.

Mention any other details that might be useful

My TSLint configuration is in tslint.yaml file and ng lint works fine. Still ng generate --fix-lint gives error complaining tslint.json file is not present:

$ ng generate component shared/dropdown --lint-fix
Asked to run lint fixes, but could not find a tslint.json.

This is not consistent with ng lint nor with official tslint tool, as TSLint can be configured both in JSON and in YAML. Quoting official documentation:

When using the CLI or many third-party tools, a file named tslint.json or tslint.yaml is used to configure which rules get run and each of their options.
