[FEATURE] Add unknown parameters to a GET request

Is your feature request related to a problem

I don’t think it’s a problem. It’s a nice and useful feature that I don’t find mentioned neither on the docs nor by searching.

The solution you would like

The basic idea is to have some parameters of GET requests that are not known in advance. It would be nice to be able to access them, along with predefined parameters (as in this case is limit)

@app.get("/")
async def my_func(limit: int = 0, **kwargs):
    var1 = kwargs["var1"]
    print("Limit is {}".format(limit))
    return {"data": var1}

# Generate a request to the url http://my_domain?var1=hi&var2=hello&limit=10
resp = testclient.get("my_domain", params={"var1": "hi", "var2": "hello", "limit": 10})
assert resp.json()["data"] == "hi"

Describe alternatives you’ve considered

I thought about accessing the raw request, but I can’t find how. Also it’s not a clean way of doing it.

Additional context

Instead of **kwargs, another name may be used, such as params

Namespaced variable would be safer here I guess. Alternatively you could just use request.query_params.
