Description

Hello! Trying to add @JsonIgnoreProperties(ignoreUnknown = true) annotation to all the generated model classes.
Trying to accomplish by adding the configuration property: ignoreUnknownJacksonAnnotation
But it seems that it simply gets ignored. I have generated swagger-codegen-cli.jar from the master branch. It appears that this should be an out of box solution.

Please help!

Research direction

Start by running the generated swagger-codegen-cli.jar with ignoreUnknownJacksonAnnotation enabled and inspect the generated model classes. Trace how that configuration property is handled and compare the output with the expected @JsonIgnoreProperties(ignoreUnknown = true) annotation. Done means the property reliably changes generated models as requested.
