CORD-389 Fix for Accton 6712 deployment

Related to this topic:
- Disable the meter collector since right now it is not supported
- Implement extension VLAN ID selector/treatment for OFDPA
    Since it requires two special flow entries to match untagged packets
        0x1ffe/no mask (filtering rule, need to go first)
        0x0000/0x1fff setvid 0x0ffe (assignment rule, need to go second)
- Not able to point /32 IP address to ECMP group. Use /31 instead.

In addition:
- Implement serializer for ExtensionCriterion
