Right now, the command to delete a connector is kcctl delete <connector name>. This is rather irregular, as for all the other command, the resource to act on is to be given as a sub-resource, e.g. kcctl pause connector <connector name>. Arguably, this is a bit more to type for those cases where there only is one kind of matching resource, but I still believe this is the better approach for the sake of regularity (e.g. kcctl get ... supports multiple resource types). I therefor suggest to apply the same reasoning to delete and change it into kcctl delete connector <connector name>.
