Bug 7952: ACLService to treat Ethertype=IPv6 and Protocol=icmp as a request for ICMPv6

In Neutron, "Protocol=icmp" is allowed to be configured with "Ethertype=IPv6"
for backward compatibility reasons. When such a rule is configured, Neutron
IPTables Firewall Driver (i.e., reference implementation) treats this as a
request for ICMPv6 and configures a rule accordingly. This patch implements
the same thing in ACLService. Please refer to the bug report for more details.
