Documentation around webpack configuration unclear

[cmeyertons]

EDIT: - I was running under 0.3.0 due to #57 not working, so I'm unblocked (although I'm having to go through some gymnastics in order to properly set the flag myself). I think this issue is still valid as a full vue.config.js would be more clear.

The documentation is unclear how exactly to leverage VUE_CLI_SSR_TARGET properly. It introduces a variable api that is unexplained. Could we expand the context to a full vue.config.js file that contains the necessary webpack configuration?

My use case is having a different URL used in a dockerized app -- the client bundle uses the full domain, while the server bundle uses the internal service name which is faster.

Here's my stripped down vue.config.js for reference:

const path = require('path')
const fs = require('fs')
const express = require('express')

module.exports = {
    devServer: {
      port: 3000
    },
    pluginOptions: {
      ssr: {
        host: "0.0.0.0",
        port: 3000,
        // Entry for each target
        entry: target => `./src/entry-${target}.ts`,
      },
    },
    configureWebpack: config => {
        console.log(`configure VUE_CLI_SSR_TARGET: ${process.env.VUE_CLI_SSR_TARGET}`)
        return config;
    },
    chainWebpack: config => {
        console.log(`chain VUE_CLI_SSR_TARGET: ${process.env.VUE_CLI_SSR_TARGET}`)
        return config
    }
}

And the console output:

yarn run v1.15.2
$ vue-cli-service ssr:build
chain VUE_CLI_SSR_TARGET: undefined
configure VUE_CLI_SSR_TARGET: undefined
chain VUE_CLI_SSR_TARGET: undefined
configure VUE_CLI_SSR_TARGET: undefined

I also found this unclear. Just proposed #142. Does that help with this issue?
