Refactor getIntegerProperty and isPropertyEnabled methods into Tools 

- Add getIntegerProperty and isPropertyEnabled methods which take
  default value as third parameter
- Remove all duplicated code from RefactiveForwarding, GroupManager,
  FlowRuleManager, CoreManager, HostLocationProvider and ProxyArp
