End-to-end test of the peer-to-peer (p2p) file sharing system.

The test runs with a main DUT and a companion DUT. The main DUT generates a
random file and shares it via p2p. The companion DUT searches for and
downloads the file.

To simulate a progressive download of the shared file, the
file becomes available in two parts. The first part of the file is available
at the beginning of the test, while the second part appears later.
