[Feature] Make CLI handle updating webpack configs

Is your feature request related to a problem? Please describe.
When I upgraded to a new version of dev-Webpack; I almost missed the message about
using "./node_modules/.bin/update-ns-webpack --configs" to update my config file... It scrolled right off the screen.

Describe the solution you'd like
tns webpack clean which would reset the config files...

possibly in addition: tns webpack update which would install @latest of the dev-webpack

Describe alternatives you've considered
None, the idea is to make the cli handle it... 😀

Additional context
Shouldn't have to deal with other tool; the CLI should handle it...

Comienza localizando el manejo de la CLI para tns webpack y el flujo de trabajo existente update-ns-webpack --configs. Determina si clean debería restablecer los archivos de configuración y si update debería instalar la versión más reciente de dev-webpack; se considera terminado cuando los comandos de CLI compatibles sustituyen a la herramienta independiente sin perder el comportamiento previsto de actualización de la configuración.
