AWS install failed not clear

[nzoschke]

I did one install through the UI that failed for unclear reasons.

CREATE_FAILED Network AWS::CloudFormation::Stack ERROR: Embedded stack arn:aws:cloudformation:us-east-1:132866487567:stack/qa10-Network-13HKR6IG0WYEH/62b70480-7706-11e7-a103-503acac5c0fd was not successfully created: The following resource(s) failed to create: [Vpc].`

Through CF deleted stacks I can see that the root cause was The maximum number of VPCs has been reached.

It would be nice to bubble sub-stack errors up.

Would be nice but complicated and doesn't seem like a blocker
