Automate config distribution between servers

Registered by David Hadas on 2013-02-12

What:
Automate the distribution of files to the /etc/swift of Swift servers.
This may include ring files as well as various configuration files.
This enhancement ensures that configuration converges to be identical in a large population of servers.

How:
 - Use rsync for data transfer
 - In the fault free scenario, design for a fast global update to N servers, using only N updates, with each server updating two other servers, and the global update taking log(N) steps.
 - Use a gossip algorithm for convergence after faults.
 - Offer configurable randomized slowdown parameters to help control the global resources used by the update and synchronization.
