feat(@angular/cli): remove direct support for cnpm

This change removes the direct support for cnpm within the Angular CLI.

BREAKING CHANGE: The `ng` commands will no longer automatically detect and use `cnpm` as the package manager. As an alternative use the `.npmrc` file to ensure npm uses the cnpm registry.
