make error readable for user - not only confusing stacktrace

See original GitHub issue

I would expect with a yaml:

jenkins:
  systemMessages: "Jenkins configured automatically by Jenkins Configuration as Code Plugin\n\n"

I’ll get a warning from dryrun saying the file is not applicable - it’s systemMessage, not a plural systemMessages. Is this how dryrun should work? 😃

Instead I get this stacktrace:

Even from a technical point of view we prevented configuration to be applied using the check method, this is indeed very disappointing for end-user, and might even let him feel like we just broke his installation. We need to offer something comparable to FormValidation with relevant diagnostic message
