BREAKING CHANGE: `css.modules` option has been removed. To import css files (or
any other supported pre-processor files) as CSS Modules, append the request
with a `?module` resourceQuery.
BREAKING CHANGE: Upgrade wepback 4, all webpack option
modifications must be webpcak 4 compatible. Drop support
for webpack plugins that do not work with v4 or above.
BREAKING CHANGE: the "vueLoader" option has been removed. To modify vue-loader
options, use chainWebpack then `config.module.rule(vue).use(vue-loader).tap()`.
vue-loader has been upgraded to v15 and expects different options from v14.
BREAKING CHANGE: PluginAPI.setMode() has been removed. Instead, for a plugin to
sepcify the default mode for a registered command, the plugins should expose
`module.exports.defaultModes` in the form of `{ [commandName]: mode }`.
