Add ping.py so we can test when a host is up. ping -c 2 -w 90 will almost do the right thing, but will exit on a icmp host unreachable. We need to continue to wait. ping.py just waits for an answer to a ping. Parallelize building the compute nodes (but not the head node). Kill ping process in ping.py. Copy PIP cache to host before running. Add syslog artifacts. Remove known_host weirdness, depend on .ssh/config instead. Change-Id: I65a12074cf80feb3ae69d15c81ba32a81566b22a
