Implements a Ping from this eNMS instance to the selected devices from inventory using either ICMP or TCP.

Configuration parameters for creating this service instance:

• Protocol: Use either ICMP or TCP packets to ping the devices.
• Ports (TCP ping only) Which ports to ping (should be formatted as a list of ports separated by a comma, for example "22,23,49").
• Count: Number of ping packets to send.
• Timeout Seconds to wait before declaring timeout.
• Ttl Time to Live parameter, which tells routers when to discard this packet because it has been in the network too long (too many hops).
• Packet Size Size of the ping packet payload to send in bytes.
