* Minor refactoring in the original FlowManager logic when setting
  the Flow Entry Switch State (for new Flow Entries):
  - The appropriate state is not hardcoded anymore inside class
    FlowDatabaseOperation. Instead, it is explicitly set by the caller method.

* Add new method FlowManager::pushModifiedFlowEntries() that is used
  by the PathComputation to push the modified flow entries to the switches
  controlled by this instance.
  Eventually, this method will be one that needs to be
  modified/refactored/adjusted to use the forthcoming FlowSynchronizer module.
  For now, the method is disabled, so it doesn't conflict with the
  existing FlowManager mechanism.
