Tests failing often due httpbin.org timeout

[blenzi]

Many pytest jobs are failing with

    def test_post_request():
        response = post_request("https://httpbin.org/post")
>       assert response.status_code == 200
E       assert 504 == 200
E        +  where 504 = <Response [504]>.status_code

Is there an alternative site, could the timeout be increased or maybe this is tested indirectly elsewhere? @frgfm

The easy fix is to increase the timeout, by passing the number of seconds to post_request. But it's already at 10sec, so it's strange that the request doesn't go through 🤔

No longer apply since #322
