This prevents centos tests from timing out because sshd does reverse dns lookups on every session being established instead of doing it once on the acutal ssh connection being established. This is odd. Appending this to the sshd config and restarting it seems to fix it though. Signed-off-by: Christine Dodrill <xe@tailscale.com>
