When you click on Host#edit Submit button, a few orchestration tasks will be created. After that, the show page will call (via AJAX) a few URLS to fetch 'overview', 'resources', 'nics', etc... to fill up the table on the left side. These are all irrelevant to tests that only concern the form, and pose a problem.

Problem:
The server we test on is not multithreaded, these tasks will run sequentially. Therefore, the default Capybara waiting time, or Capybara.default_max_time might not be enough to wait for all requests.

Solution:
We can stub out these calls, and wait until the #host-progress div has disappeared for POST/PATCH requests.
