 Description   

I think an existing but static variable should give a different error when tried to be set dynamically, what we have now is:

$ maxctrl -u user1 -p 123 -h 127.0.0.1:8989 alter maxscale log_augmentation 1
 
Error: Server at 127.0.0.1:8989 responded with status code 403 to `PATCH maxscale`:{
 
    "errors": [
 
        {
 
            "detail": "Unknown global parameter: log_augmentation=1"
 
        }
 
    ]
 
}

Same message as with a totally non-existing parameter:

$ maxctrl -u user1 -p 123 -h 127.0.0.1:8989 alter maxscale something_random 123
 
Error: Server at 127.0.0.1:8989 responded with status code 403 to `PATCH maxscale`:{
 
    "errors": [
 
        {
 
            "detail": "Unknown global parameter: something_random=123"
 
        }
 
    ]
 
}

Also error message perhaps could be formatted better, e.g.:

Error: Server at 127.0.0.1:8989   Code 403 : "Unknown global parameter: something_random=123"
