Create new ping command with the following semantics
1. ping <ipv4|ipv6|hostname> will use
* ping for a v4 address
* ping6 for a v6 address
* ping or ping6 for a hostname which ever resolves prefering ipv4
2. ping ipv4 <ipv4|hostname> will ping
3. ping ipv6 <ipv6|hostname> will ping6
4. ping <node> option <advanced ping options>
* allows for options to pass down to ping
* this is a stop gap while we add the most common options
* to the CLI
