Add build option to set publicPath

What problem does this feature solve?

I’m trying to deploy a Vue.js application to Github Pages. Github Pages deploys to a URL that looks like username.github.io/repo-name. The problem is that the vue-cli-service build command builds links that look like /js/vendor.2e8c48c3.js rather than repo-name/js/vendor.2e8c48c3.js or ./js/vendor.2e8c48c3.js.

There is a webpack option, publicPath, that I’m pretty sure is the solution, but there isn’t a way to set that option with vue-cli.

https://webpack.js.org/api/cli/#output-options https://github.com/webpack/docs/wiki/configuration#outputpublicpath

What does the proposed API look like?

vue-cli-service build --publicPath='/repo-name'

Use baseUrl option in vue.config.js.

@johansaldes baseUrl is a top level property, not a devServer option.
