Validate runtime configuration before executing the runtime

Properties are validated by studio integration to check @Require @Min @ Max and so on.

It would be great to enable the validation at runtime to have understandable message if a value is wrong before executing the job.

It seems that johnzon has some validator options: https://github.com/apache/johnzon/blob/master/johnzon-jsonschema/src/main/java/org/apache/johnzon/jsonschema/JsonSchemaValidatorFactory.java#L87
