Update .com trial signup process

Problem

As a user, when I signup for a trial, the process is convoluted, complex and confusing. I don't understand why I have to create 2 accounts in order to signup. I would rather try to figure out how to use the product for free rather than invest my time trying to figure out how to pay.

Solution

Move trial signup into gitlab.com.

Idea

Goals

• At signup the user should never know that a second application exists that manages their trial
• The user should not have to create a password or profile for customers.gitlab.com
• The user should be able to log into customers.gitlab.com using a code that is texted to their phone (rather than password)
• The user should be able to log into customers.gitlab.com using a code that is emailed to their address (rather than password)
• If the user is a part of this test, when linked to customers.gitlab.com from their instance, they should be taken to a signup page that does not prompt them for a password
• The user should never have to manage a trial license key
