swagger api's generated auto by loopback v3

@ElfenLiedGH this is because by default you can pass a parameter options with a configuration object. A quick solution to your problem is to rename your options to e.g. streamOptions.
this issue is somehow similar to #7911, since we have naming conflicts with kind-of reserved keywords / names.

@macjohnny it's autogenerated api from IBM strongloop, i can't change any format

[macjohnny]

@ElfenLiedGH would you like to give it a try and implement a fix similar to #7916 ?
