Ok, sounds good.

We need to understand what is the common way in openstack to work with 
deprecated code.

Hi, Alexey

I plan to split the implementation to several steps, because it will take weeks 
to complete. I'm afraid it would be too big a patch to review if I submit all 
changes in one patch set.

Instead I want to get comments as earlier as possible. Each submit will be 
covered by additional unit test and keep backward compatibility.

Detail replies inline.

Hi Yujun,

Good job! This is a very important change for Vitrage.

I have a couple of questions please:
1. Why do we want to create a new datasource ‘static’ and not rename the 
current ‘static_physical’ datasource and change it to work with the new format?
I don't want to break it during the evolution.
2. How are you planning to use the old 'static_physical' datasource  as a proxy 
if you said that you want to remove it?
Good point. Any suggestion on how we hide the deprecated modules? Move it as a 
submodule in new module.
3. What kind of merge is needed in the evaluator?
Parsing of `definition` section would be a common module for both evaluator and 
static data source 
4. I saw the implementation of the driver.py in static, and it doesn't do 
anything at the moment? (if you are still working on one of the patches then 
please market it as -1 in the code-review that we will know that you are still 
working on it.
Yes, skeleton is skeleton. Since I'm working remotely with vitrage team. I want 
to keep you updated on the progress. Still, it is complete with unit test and 
backward compatibility and will reduce further review work.
