[copp] add dhcpv6 copp rules (#1979)

What I did Add secondary COPP config file to enable DHCP V6 (1) need to create a new table, (2) so that the warm reboot asic config checker won't flag it as a configuration change and prevent warm reboot. (3) warm reboot finalizer can selectively just apply the second file. Why I did it Need to enable DHCP V6 How I verified it Warm reboot from a version without it to a version with it. Warm reboot from a version with it to same version. Cold reboot. In all 3 cases, dhcp v6 rules are correctly installed. Signed-off-by: Ying Xie <[email protected]>
