[JENKINS-34105] Add support for parameters of type java.util.Set

TriggerOnSpecifiedImageNames from the Docker Hub Notification plugin has a parameter with type Set, see source.

Instantiation will fail due to argument type mismatch when passing a Groovy list literal. It would be nice if the list would be coerced to a set automatically.

import org.jenkinsci.plugins.registry.notification.opt.impl.TriggerOnSpecifiedImageNames 

import org.jenkinsci.plugins.structs.describable.DescribableModel


def m = new DescribableModel(TriggerOnSpecifiedImageNames)

m.instantiate([repoNames: ['foo', 'bar']])

java.lang.IllegalArgumentException: argument type mismatch
