api: document w (width) and h (height) query params as required

Query parameters default to being _optional_ in swagger, but for these
endpoints, they were required. Omitting these parameters (or passing an
empty value) produces a 400 (bad request);

    docker run -d --name foo nginx:alpine

    curl -XPOST --unix-socket /var/run/docker.sock 'http://localhost/v1.47/containers/foo/resize'
    {"message":"strconv.Atoi: parsing \"\": invalid syntax"}

    curl -XPOST --unix-socket /var/run/docker.sock 'http://localhost/v1.47/containers/foo/resize?w='
    {"message":"strconv.Atoi: parsing \"\": invalid syntax"}

    curl -XPOST --unix-socket /var/run/docker.sock 'http://localhost/v1.47/containers/foo/resize?w=&h='
    {"message":"strconv.Atoi: parsing \"\": invalid syntax"}

    curl -XPOST --unix-socket /var/run/docker.sock 'http://localhost/v1.47/containers/foo/resize?w=100&h='
    {"message":"strconv.Atoi: parsing \"\": invalid syntax"}

    curl -XPOST --unix-socket /var/run/docker.sock 'http://localhost/v1.47/containers/foo/resize?w=100&h=100'

This patch amends the swagger to reflect that these parameters are required.
