request.url_vars helper property

This example: https://github.com/simonw/datasette/blob/f5e79adf26d0daa3831e3fba022f1b749a9efdee/docs/plugins.rst#register_routes

from datasette.utils.asgi import Response
import html


async def hello_from(scope):
    name = scope["url_route"]["kwargs"]["name"]
    return Response.html("Hello from {}".format(
        html.escape(name)
    ))


@hookimpl
def register_routes():
    return [
        (r"^/hello-from/(?P<name>.*)$"), hello_from)
    ]

Would be nicer if you could easily get scope["url_route"]["kwargs"]["name"] directly from the request object, without looking at the scope.

Currently querystring parameters are accessed through request.args and POST variables through request.post_vars(). Would be good to have a name that was somewhat consistent with those.

I'm leaning towards request.url_vars.
