Change ping wait flag
This is an optimization of the ping command. It changes ping test from waiting for a single sent packet for 300 seconds to waiting to receive a packet from any number of sent packets. The current implemenation waits for full 300 seconds before retrying if we do not get a reply for the first packet sent. By using -w flag, we keep sending icmp packets until a reply is sent, making the ping test more responsive to connectivity change.
