[RFC 638] Interactive way to create new Ember apps and addons

[bertdeblock]

RFC PR: emberjs/rfcs#638

Went with inquirer for the following reasons:

• Development of enquirer seems to have stalled
• prompts seems nice as well, but inquirer is more populair (based on download and GH star count)
• inquirer seems to be the most active library at the moment

Result:

I overlooked some tests, e.g. ember help output, will fix asap!

excited to try this out!

Can't seem to figure out why CI is failing at the moment.
It seems this line is the culprit:
https://github.com/ember-cli/ember-cli/blob/master/tests/acceptance/smoke-test-slow.js#L236-L237
It hangs, and thus the timeout is exceeded.
Seems to fail here as well:
https://github.com/ember-cli/ember-cli/runs/5564343698?check_suite_focus=true#step:5:2237

Really excited for this!!! An interactive mode is so clutch for folks new to programming and are extremely intimidated by help screens and cli flags.

(It's also just a nice way to walk folks through stuff)

Glad you're excited 😄 I just need to know what to do about #9824 (comment).

Overall this looks great, thanks for working on it!!

I left a couple inline questions/suggestions, and I think we need at least one test that goes through a full flow "acceptance" / "slow" test that actually runs ember new and enters the values for the prompts (to make sure that things actually work in reality).

[bertdeblock]

Addressed the smaller issues, still need to come up with an acceptance test that completes the entire flow.

[bertdeblock]

In case anyone is following along, I could use some help writing a full acceptance test where we simulate user input.

Discussed in the ember-cli meeting today, we've decided not to block on the interactive testing but hope to add that test coverage later.
