Fetch resources in parallel
Summary
=======
Speed up resource fetching using futurist library and GreenThreadPool
Motivation
========
On several tabs (e.g. networks, qoutas) we have to call different server APIs to fetch all needed data. We can do it in parallel to mage pages rendering faster.
Description
=========
Futurist library and GreenThreadPool
Testing
======
Current tests should be enough to verify that nothing is broken.
Outside Dependencies
==================
Futurist library is already including to requirements.txt, we need to add eventlet to get GreenThreadPool

Make API calls in Volumes view parallel
Could you show the fact that how making fetching resources in parallel contributes the speedup? Does futurist used in the proposed review use native threads rather than python greenthread? If so, this changes the way of optimization as it changes the balance of apache configurations like the number of processes or workers. At a first glance, I am not sure at all how this contributes the total performance. -- amotoki
