Prompt user for Maps ID

Prompt user during ignite add maps

Google Maps on Android requires an API Key.  This can be acquired from 
https://developers.google.com/maps/android/?authuser=1

What would you like to do?
> Enter my Google Maps API key
  Borrow a key promise to never push that to production 🤞
  Skip it! I'm not supporting Android

Option 1: We insert the key for them.
Option 2: We insert the same old key we've been using since Ignite 1
Option 3: Show them the friendly message like we added in #7

That's a cool idea, @GantMan !

We're on the hook for the API key usage, so let's skip option 2. It's tied to our account, so if we were ever to turn on billing, then hilarity would ensue.

Also add a --skip-question mode for people installing this via a boilerplate and want automation.

But ya, how great would option 1 be when you're getting going? 💯

Not sure about this one, but will this also help getting Google Maps on iOS? Would be nice if that's also an option when installing!
