[CORD-2531] Missing flows and multicast groups

The rationale for this change is: unhandled exceptions
prevent Runnable to be scheduled in future.
We need to protect the body of runnable.

Related to [CORD-2532] and [CORD-2533].

In the pipeliner we use checkers and groups listener
to get notification about groups. The error scenario:
unhandled exception in the context of a group checker
will kill the checker. We create a multicast group, which
requires firstly a l2interfacegroup. The latter has been
already created in the past. No notification from groups
and no checker -> failure. Multicast group is not created
and forwarding objective in pending (forever).

Potentially, it can fix other errors scenario.

ONOS : Open Network Operating System

What is ONOS?

ONOS is a new SDN network operating system designed for high availability, performance, scale-out.

Top-Level Features

  • High availability through clustering and distributed state management.
  • Scalability through clustering and sharding of network device control.
  • Performance that is good for a first release, and which has an architecture that will continue to support improvements.
  • Northbound abstractions for a global network view, network graph, and application intents.
  • Pluggable southbound for support of OpenFlow and new or legacy protocols.
  • Graphical user interface to view multi-layer topologies and inspect elements of the topology.
  • REST API for access to Northbound abstractions as well as CLI commands.
  • CLI for debugging.
  • Support for both proactive and reactive flow setup.
  • SDN-IP application to support interworking with traditional IP networks controlled by distributed routing protocols such as BGP.
  • IP-Optical use case demonstration.
