CodegenResponse.java should contain `is<DataType>` boolean fields

[abaruni]

In order to more thoroughly support any type of response defined in an Open API spec, CodegenResponse.java should contain isString, isDouble, isInteger, etc, etc. This will allow handling responses from the server at a more granular level

@abaruni yes, we want to do the same to CodegenParameter and CodegenProperty as well.

May I know if you've time to contribute the enhancements?

@wing328 yes, i've got time to contribute the enhancement

the properties already exist in CodegenParameter and CodegenProperty:

@abaruni yes, you're right. The funny thing is that I added those. I'm getting old...
