[Feature Request] Add alternate output option

I’m submitting a feature request

• Library Version: 0.23.0

Please tell us about your environment:

• Operating System: Windows 10

• Language: ESNext

Current behavior: It is currently not possible to change your output directory when running au build.

You are currently unable to change it through editing the build tasks, because the CLI bundler will use the new output path when finding & replacing the script tag src in index.html. It won’t be able to update the vendor-bundle src.

https://github.com/aurelia/cli/blob/master/lib/build/bundle.js#L217

Expected/desired behavior: The ability to specify the output directory for a build, depending on the environment.

We tried with the following snippet inserted in the build.js task, but it was unable to update vendor-bundle in the index file.

import {CLIOptions, build} from 'aurelia-cli';
import project from '../aurelia.json';

if (CLIOptions.hasFlag('output')) {
    project.build.targets[0].output = CLIOptions.getFlagValue('output');
}

• What is the expected behavior? The command au build --env prod --output export Should output to the directory export

I feel like we should look at changing the way CLI updates the path to vendor-bundle. Maybe the setIndexFileConfigTarget part should be a task that the developer can edit themselves?

@CasiOo If there are ideas behind targetS (as in more than one) I couldn’t find anything in the code (which only uses targets[0]). The au build should now however work with anything after --env so it would be possible to build web, cordova or electron with this. (Or even cordova-dev, electron-prod and so on.)

Furthermore, aurelia.json seems to currently only support one platform per project. I think there’s more to do if we’re to have true multi platform projects. And that might also include a --platform flag for the build command, making it, for example, au build --platform cordova --env dev --watch for multi platform projects.
