Make query options immutable

[skovbasa]

Having a query:

query Test($params:Any){
  someLink(params: $params) {
    params
  }

  someOtherLink(params: $params) {
    params
  }
}

Where params is some mutable object (dict for example), it is possible to mutate params in someLink and someOtherLink will see that change.

I feel like it should not be acceptable and opts need to be of immutable type
