Detox: point to a single configuration file

[oreporan]

Description

Currently it seems that detox allows configuring only in the package.json of the project. But using a mono-repo (lerna), we want to run detox in specific packages. However I don't want to duplicate our detox config in each package.json
I've seen a discussion in https://github.com/wix/detox/issues/175 but it doesn't mention creating the file outside the package.json
Possible solution:

detox-config.json

Detox, Node, Device, Xcode and macOS Versions

• Detox: 8.0.0
• Node: 8.9.4

you can do this in the current build

const config = require('../config').detox;
await detox.init(config);

Unless I put a detox and configuration object in my package.json, I still get:

 if (_.size(config.configurations) === 1) {
                    ^
TypeError: Cannot read property 'configurations' of undefined
    at getDefaultConfiguration (/Users/ore/env/dev/repos/x/node_modules/detox/local-cli/detox-test.js:207:21)
    at Object.<anonymous> (/Users/ore/env/dev/repos/x/node_modules/detox/local-cli/detox-test.js:23:151)

This is due to

detox/local-cli.js
const config = require(path.join(process.cwd(), 'package.json')).detox;

You're right, we should give an opportunity for users to get an external config file, not only in package.json.
Logic may try getting config from package.json, and failover to a config file (or vice versa).

A PR is most welcome!

@oreporan , check what's inside of your detox/tests/package.json. Maybe you modified something?

Sorry, I found the issue and removed the comment :)
