Mechanism for Auto Selecting Blueprint via Answers File

Is your feature request related to a problem? Please describe.
This is not a problem but it would help enhance my process. Why select a blueprint when I can have it in my answers file. The answers file would document itself. No need to manually specify a Blueprint. Also if I create an answers file it would use that particular Blueprint hence why it would make sense to include the Blueprint to select in the answers file.

Describe the solution you'd like

massimo@ubuntu:~/data-factory cat answers.yaml
Blueprint: my-blueprint
AppType: data_factory
UseAppInsights: true

massimo@ubuntu:~/data-factory xl blueprint --use-defaults --answers answers.yaml
? Choose a blueprint:  [Use arrows to move, type to filter]
> my-blueprint

It would be nice to get rid of the prompt by having the Blueprint set inside of the answers.yaml file.
