[Request] Support for `vue-cli-service serve [entry]` command equivalent

Vue CLI has support for [instant prototyping](https://cli.vuejs.org/guide/prototyping.html#vue-serve). `vue-cli-service serve [entry]` command can directly serve single file component or js file. 
I'd love to see an equivalent feature from Quasar CLI that automatically loads quasar.conf.js and serves a file. It would greatly help to prototype a new component. 
Thanks for the great tool!
