AWS Quickstart support

[cliffano]

Is your feature request related to a problem? Please describe.
We would like to be able to create a vanilla AEM Full-Set and AEM Consolidated via AWS Quickstart as the entry point.

Describe the solution you'd like
This requires the introduction of new CloudFormation templates which combine the prerequisites and main of AEM Full-Set and AEM Consolidated templates, with additional smarts on the parameters:

• predefined fixed list of parameters to select (e.g. region selection)
• dynamically retrieved list of parameters (e.g. AMI IDs selection)

Other than the existence of new CF templates, we also need to modify the Makefile:

• add new make package-quickstart which should create stage/aws-quickstart/ dir which contains all the files required as per the structure needed by AWS Quickstart repo, and create a zip file of it

Describe alternatives you've considered
No alternatives because the purpose is to support AWS Quickstart.
