Validator for Deadline data

Is there an existing issue for this?

[X] I have searched the existing issues.

Please describe the feature you have in mind and explain what the current shortcomings are?

There should be validator checking if data set for various Deadline attributes is correct. For example, you can still submit job with priority set 101.

How would you imagine the implementation of the feature?

It should have basic type checking and some sane value checking, at least for static attributes.

Are there any labels you wish to add?
