In addition,
- Block ARP/NDP on pair port from being sent to controller
- Block DAD on pair port from flooded back to the originated host
- Minor refactoring

Introduces the concept of edge-pairs (or paired-ToRs) which
can have some subnets/prefixes reachable by both ToRs.
- Each ToR can also have prefixes reachable only by itself,
even though it is part of an edge-pair.
- The paired link between ToRs in an edge-pair is ignored
for ECMP calculations.
- Required a change in how destinations and next-hops are stored.
The neighborSet is now a destinationSet, and no longer carries
next-hop info, which is now stored in NextNeighbors. As a result,
the DestinationSetNextObjectiveStoreKey and ECMP group id do not
change as next-hops come and go.
- It is now possible to have buckets in hash groups with the same
outport but different labels.
- DefaultRoutingHandler has been rearraged to be more readable, and
clearly highlight the three major ways that routing changes can
happen in the network.
Also fixes the case where config is added after switches connect to the controller.

- DHCP relay doesn't set destination MAC properly when forwarding the reply
- SR doesn't properly turn off the arp handler in dhcp relay

- to better align with current BUCK behaviour which only includes java sources
- and few other pom fixes

Also removing some old demo code in the SR app
Adding a couple of CLI commands for debugging
Bug fix in the DistributedGroupStore for group_exists error message
Bug fixes for ofdpa driver:
- synchronized update of flowObjectiveStore when buckets are added to or removed from groups
to avoid one thread from overwriting an update from another thread doing an update at the same time
- addBucketToL2FloodGroup now updates flowObjectiveStore after accounting for changes
- addBucketToHashGroup accounts for all added buckets, not just the first one

SR now offers a clean way to config OLT control and data plane traffic.
For OLT data traffic, we can use vlanTagged config.
For OLT control traffic, we can use vlanUntagged/vlanNative + host config.

Next-objectives that edited groups are now queued in the FlowObjectiveManager instead of the driver.
During linkup immediately checking for previous portups that should be added to a hash group.
A final retry 30 secs later to catch all ports that should be part of the same hash group.

We had this limit before because we derived VLAN from subnet.
We no longer do that and thus user should be free to config 0+ IPv4/IPv6 addresses
Change-Id: I144c618112e4b437ebf64ea3b5ab05a83263cb17
Also changing pendingGroups to a cache that will automatically purge failed groups
Improving log messagesin several places
Change-Id: I6843a66d58e623259c7fd20ffe64d56a46d963f0
- No longer handle ICMPv6 packets except those target routerIP and gatewayIP
- Remove source IP validation for ICMPv6 since IPv6 hosts often speak with their link local address

A direct link might be transiently marked as indirect if BDDP is received before LLDP.
SR needs to handle link updated event such that it can process when an indirect link becomes direct.

Major changes to the DhcpRelay app
Bug fix to not depend on global variables that can be overwritten
App is now vlan aware i.e. client and server can be in different vlans
Added probing of dhcpServer to get mac/vlan instead of configuring these values
Added optional gateway IP for cases where dhcpServer is "behind" external router
Added support in host monitor for trunk vlan configurations
Javadoc fix in Interface.java
Commented out unused log message in HostLocationProvider
Bug fix to make ALL group editing vlan aware.

In the scenario where subnets and hosts are configured,
flows for forwarding/flooding should be provisioned.
A copy from the control plane will only cause duplication.
Therefore we are turning that off for now.
We might want to revisit this if we want to support ARP/NDP learning in the future.
