Recent commits result in Welcome email being sent long before stack creation is complete

[rstrahan]

Expected Behavior

Welcome email indicates that user can log in to Content designer, and start using QnABot.. When user receives this email, stack should be ready for use.

Actual Behavior

After recent updates, the stack create continues long after the welcome email is received.. If user logs in and uses QnABot after receiving the email, it can cause problems with ElasticSearch/Kibana setup since stack is not finished building.

• Send email only when stack creation is about to complete

fix is coming in 2.1.0 version

[rstrahan]

The develop branch does not appear to have a fix for this issue. Since the email is sent when user pool is created, and the user pool is a dependency for the ElasticSearch update to add Kibana auth, it's not clear to me if we can delay the welcome email until rest of stack is complete.
For now i will simply update the email text to tell user to wait till stack is complete.

New text:
