Controller now needs to listen for storage notifcation and it will
dispatch updates if the controller node IPs change.

We now have three different types of updates in the Controller.updates
queue ==> Refactored to use different update classes that implement a
common IUpdate interface instead of a several types and a switch
statemet.

Add unit test for Controller.updates queue

Retab that caused some unrelated chagnes but now now more tabs:
    flconext, addInfoProvider, removeInfoProviderm getControllerInfo

Retab also causes changes in flcontext: that's only indentation.

Needed to touch quite some files to refactoring: rename
IHARoleListener -> IHAListener

[#29035681]

Add a config parameter to change the port the Jython server runs on. (https://github.com/floodlight/floodlight/pull/106)

Note: Switch stats don't update yet...not sure why...coming next.

    topology ui: more error checking  (https://github.com/floodlight/floodlight/pull/105)

    topology ui: show vendor names in switch view  (https://github.com/floodlight/floodlight/pull/104)

topology ui bugfix: don't assume hosts have ips (https://github.com/floodlight/floodlight/pull/103)

topology viewer was dying if floodlight had not yet discovered
an IP address for every host.

Add support for generating test coverage using cobertura (https://github.com/floodlight/floodlight/pull/102)

Enhance TopologyManager REST API. (https://github.com/floodlight/floodlight/pull/101)

Removing a couple placeholders unlikely to be filled in for the near future.  Would be great to get uptime but have no api for it right now.

Online javascript files (https://github.com/floodlight/floodlight/pull/99)

Reenabled the mechanism for initializing the HA role of the controller from a file (https://github.com/floodlight/floodlight/pull/100)

Change host/switch identification to use IDs instead of names in web topology view.  Add last seen host IP address.

Wait instead of sleep in unit test (https://github.com/floodlight/floodlight/pull/96)

minor toString fix in Device

Move the switch learning table out of IOFSwitch and into the LearningSwitch module. (https://github.com/floodlight/floodlight/pull/95)

2 - Move the learning switch table outside of the IOFSwitch and into the LearningSwitch module.
3 - Create a REST API for the LearningSwitch module to get the learned table. Available at "/wm/learningswitch/switch/{DPID or 'all'}/json".

Fix race condition in device AP learning with topo change, and remove DM from link events.

Correct race condition in device learning and topology, remove deviceManager from listening linkEvent
