Description

@phobologic had a good idea - forcing a type on a lookup.

This would allow you to cast things on the fly:

Example:

${force_type <value>::<type>}

Research direction
Investigate stacker's variable resolution mechanism in stacker/variables.py. Look for existing lookup functions like 'ref' or 'output'. Implement a new lookup function 'force type' that accepts a value and a type string. The implementation should call the appropriate type conversion function (e.g., int, float, string). Ensure compatibility with CloudFormation parameter types.
