feat(client): use object-based configuration (segmentio#7)

BREAKING CHANGE: We've dropped the chained configuration for an object one instead. This will make Analytics blend even better with tools like Prettier.

Before:
```js
analytics
    .configure()
        .using(Mixpanel, GoogleAnalytics)
        .recordScreenViews()
        .trackAppLifecycleEvents()
        .trackAttributionData()
        .android()
            .flushInterval(60)
            .disableDevicedId()
        .ios()
            .trackAdvertising()
            .trackDeepLinks()
    .setup("writeKey")
    .then(() =>
        console.log('Analytics is ready')
    )
    .catch(err =>
        console.error('Something went wrong', err)
    )
```

Now:
```js
analytics
    .setup('writeKey', {
        using: [Mixpanel, GoogleAnalytics],
        recordScreenViews: true,
        trackAppLifecycleEvents: true,
        trackAttributionData: true,

        android: {
            flushInterval: 60,
            collectDeviceId: false
        },
        ios: {
            trackAdvertising: true,
            trackDeepLinks: true
        }
    })
    .then(() =>
        console.log('Analytics is ready')
    )
    .catch(err =>
        console.error('Something went wrong', err)
    )
```
