Support enriching schema objects with property-specific information of a bean

[rpdai]

With this added functionality, the following becomes possible:

import javax.validation.constraints.Min;
import com.fasterxml.jackson.databind.BeanProperty;
import com.fasterxml.jackson.module.jsonSchema.types.IntegerSchema;

public class CrudIntegerSchema extends IntegerSchema {

    @Override
    public void enrichWithBeanProperty(BeanProperty beanProperty) {
        Min minimum = beanProperty.getAnnotation(Min.class);
        if (minimum != null) {
            this.setMinimum((double)minimum.value());
        }

    }
}

Bean validation, documentation strings, and custom schema annotation support become achievable.

This resolves #18

Ok this looks promising, thank you! I will need to read it with bit more thought, but it sounds plausible.
I will also need to see if additional method(s) could lead to deprecation of older ones.

Cool!

BTW once the API is settled on, I'm happy to look at adding support for bean validation annotations to the module or as extension module, if that'd be of value 👷
