When a dual homed host moves from [1A/1, 1B/1] to [1A/2, 1B/1], it is very likely that 1B side moves as well.
A verify probe should be sent on 1B/1 to see if the host is still there.

- Push ACL flow to ignore xconnect VLAN
- Add pair port to the L2FG internally
- Remove the ETH_TYPE restriction in OFDPA processVersatile
- Remove the NOACTION warning in OFDPA processVersatile
- Do not push bridging flow for hosts that have wrong VLAN tag
Known issue:
- flooding issue on the pair port
- tagged host will be learnt before xconnect config is pushed (will be ignored by SR)

Two main changes for the bug-fix:
- avoid doing a full-reroute in the event of link failure as this will leave behind stale state in stores
if event has been preceded by mastership change leading to the nuking of the ecmpSpg for one of the
link's devices; instead do a rehash
- when full-reroute is attempted, do it only once, with a complete nuke of the next-obj store
Improvement in group handling allows for a max number of retries for a group that failed to be added.
Earlier behavior was to try only once, and if it fails, it gets removed from the group-store. Now it
is removed after a couple of retries - so total 3 attempts to program the group.

- refactored l2 handler to *only* program initiation and termination
points and nothing else.
- all pseudowires are set to be carried wiht PSEUDOWIRE_VLAN fetched
from srManager.

- Co-ordination when creating - removing pseudowires from
different instances with a use of a DistributedLock.
- Fixed REST API To return json with specific error for
the single pw instantiation.
- Fixed REST API to return specific error also for pseudowires
that could not be decoded.
- Minor bug fix to return appropriate error when instantiating
a pw from the command line that could not be decoded.
- Fixed bug when creating spine-leaf-leaf pseudowire where we observed flows in pending state.
- Improved logging.

- Implement probe retry
- Switch to typical core/provider design pattern for HostProbingService
and as a result decoupling the dependency between SR and HostLocationProvider

The issue was in the serialization. Since we enhanced DestinationSet
to use an Enumeration class, this class should also be registered
with KryoNamespace. Without registering the Enum class
DestinationSetType, the next hops were remaining local to the instance
which has inserted them into the Map and they did not propagate to
other instances.

- Removed the booleans in destination test set and refactored
it to use a proper enumeration.
- Create a special next objective for pseudowire transport that
does not pop the tag.
- Install special filtering rules for receiving trafffic for
pseudowires in all devices.

This patch also redirects IPv6 NDP, which is also a multicast packet, to table 40. The IPv6 bridging and BGP peering break as a result. I am reverting this for now and we will need to find another way around.
This reverts commit b955fec073cd90b3b1ac4cbab51e82d110ca43d1.

Majorly for the 2nd step of [1A/x, 1B/x] -> [1A/x, 1B/y] -> [1A/y, 1B/y]
But will also cover [1A/x] -> [1A/y] -> [1A/y, 1B/y]
When receiving probe for 1A/y in [1A/x, 1B/y] state, simply replace 1A/x with 1A/y instead of creating a transient 3rd locaiton
