ONOS-2513 Fix entire MP2SP intent failing on partial connectivity loss

 * Added PartialFailureContraint to MP2SP intent to allow partial connectivity.
   This means the intent remains installed as long as at least one ingress point
   can reach the egress point.
 * Intents with this constraint are recompiled on ObjectiveTracker triggers
   even if not in FAILED state
 * MP2SP intent compiler can compute a partial tree if constraint is set
 * ObjectiveTracker recompiles intents on any link event
 * SDN-IP MP2SP intents now use PartialFailureConstraint

Ported from onos-1.2 branch.

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.
