Description

CloudFormation now allows us to enable Stack Termination Protection, which works similar to the EC2 termination protection. We can enable it while creating the stack. When termination protection is enable, CloudFormation won't delete the stack unless we explicitly disable the protection. There are more information about this in the announcement.

Research direction
Investigate the stacker codebase to find where stack creation parameters are constructed, likely in stacker/actions/build.py or stacker/blueprints/base.py. Add a new parameter to allow users to enable termination protection, then pass it to the boto3 CloudFormation client's create stack call. Ensure the parameter is optional and defaults to False for backward compatibility.
