AU P2P: Add new EndToEnd test.
This patch includes a new server side test to test the end-to-end
funtionality of the new peer-to-peer (p2p) file sharing mechanism.
The test runs over a set of N machines generating a random file
in one of them (called the "master") and sharing it with the rest
of the machines. The success condition of this test occurs when
all the N machines have the same generated file in at most a
certain timeout (currently 10 minutes).
To achieve certain inter-process communication a simplified
Barrier class is included as part of the cros library. This
Barrier class is based on the multiprocessing.Queue class and
assumes a scenario where a given process is a master, like the
one presented here, to simplify the implementation.
