dpif-netdev: add subtable-lookup-prio-get command.
This commit adds a new command, "dpif-netdev/subtable-lookup-prio-get"
which prints the available subtable lookup functions in this OVS binary.
Example output from the command:
Available lookup functions (priority : name)
0 : autovalidator
1 : generic
