fluster-on-chromeos: Simplify ssh between client and dut

Simplify `ssh` connection between client and DUT by setting the `/root/.ssh/config` to avoid using `-o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -i /home/cros/.ssh/id_rsa` flags on every connection. Keeps only the first `ssh` connection flags which waits until the DUT to be available. Signed-off-by: Denis Yuji Shimizu <[email protected]>
