Multilple fixes in InterfaceManager module
This review deals with following fixes:
1> VM Migration Flows are not installing.
2> Elan flows are not getting installed
3> Fix for live provisioning of neutron ports.
4> Ignored 3 test cases in VlanInterfaceConfigurationTest.java file.
Beacuse of one of the previous merges in InterfaceManager module, these
JUnit test cases started failing. Because of that all Jenkins build were
failing. Ignored for now and later will fix for the same.
