Custom validation should allow assigning dataPath value

[ronjunevaldoz]

Please see related issue: #35

Steps

addConstraint(dataPath = "confirmPassword") {}
// or automatically catch dataPath from field
CreateBasicAccountInput::confirmPassword required { 
  addConstraint("Passwords should match") {
       it.password == it.confirmPassword
  }
}

Actual

error :dataPath: "", message: "Passwords should match"

Expectations

error: dataPath: "confirmPassword", message: "Passwords should match"

I didn't quite see if this shows the correct answer or is it a pending wip. This is not resolve on my end

With 0.7.0 and #86 the situation will improve a bit, but this could be better

Validation<CreateBasicAccountInput> {
  validate("confirmPassword", { it.password to it.confirmPassword }) {
    addConstraint("Passwords should match") {
       it.password == it.confirmPassword
    }
  }
}

The above will have the correct path, but ideally addConstraint or similar should allow setting this directly
