CI: Add ZTS -O option, log Setup Testing Machines step

Browse Source 
Add a -O option to zfs-test.sh to dump debug information on test
timeout.  The debug info includes:

- 30 lines from 'top'
- /proc/<PID>/stack output of process with highest CPU usage
- Last lines strace-ing process with highest CPU usage
- /proc/sysrq-trigger kernel stack traces

All debug information gets dumped to /dev/kmsg (Linux only).

In addition, print out the VM console lines from the "Setup Testing
Machines" step.  We have often see VMs timeout at this step and don't
know why.
