Open Stack

Hello, 

I would like to propose some modifications regarding the Freezer core team. 

First, the removal of two inactive members:
  - Fabrizio Fresco: Inactive
  - Eldar Nugaev: Switched company and is now focusing on other projects.
Thank you very much for your contributions.


Secondly, I would like to propose that we promote Yang Yapeng (yangyapeng) core.
He has been a highly valuable developper for the past few month, mainly working on integration with Nova and Cinder.
His work can be found here: [1]
And his stackalitics profile here: [2]


If you agree with all these change, please approve with a +1 answer or explain your opinion on any of these individual modification.
If there are no objection, I plan on applying these tomorrow evening.

Thanks
- Pierre, Freezer PTL
