Pass in "Extra" Values

Feature Request

I'd like to be able to pass in values for additional properties to the MODULE types.

Example for a module named `ACME::FOO::LogGroup::MODULE`:
```yaml
Parameters:
FunctionName:
Type: String

Resources:
LogGroup:
Type: AWS::Logs::LogGroup
Properties:
LogGroupName: !Sub /aws/lambda/${FunctionName}
```

Example use case of a default property as defined by CloudFormation/API:
```yaml
LogGroup:
Type: ACME::FOO::LogGroup::MODULE
Properties:
FunctionName: !Ref SomeLambdaFunction
RetentionInDays: 3 << "Default" Property.
```
