Bug 7563: Add config for inactivity_probe and max_backoff
Fix v2.: Fixes wrong schema definition for MaxBackoff column in Controller
table. Adds two more exceptions to catch in
OvsdbOperationalCommandAggregator.
This adds support for inactivity_probe and max_backoff fields in
Controller entry. Changes to Util method for addBridge and setControllers
is done in a backward compatible way. Once Netvirt changes to new API,
older one will be removed.
