Issue
=====
Exception observed while creating CPVM in VMware Setup with DVS.
Observed error "StartCommand failed due to Exception: com.vmware.vim25.AlreadyExists."
This is due to concurrent attempts to create same dv portgroup on same dvSwitch by
manager threads of CPVM and SSVM when both are started at same time.
Fix
===
Synchronize api calls to create/update dvportgroup.
Also maintaing local cache to avoid multiple fetch api calls to vCenter
when multiple threads try to create same object.

This is 1st patch for feature 'Support for VMware dvSwitch in CloudStack'.
This contains 3 newly introduced classes. Added apache license header for all 3 files.
[1]TrafficLable and [2]VmwareTrafficLabel classes are to define and encapsulate virtual switch type per traffic type along with other network label fields (VLAN ID and physical network).
[3]DistributedVirtualSwitchMO class is wrapper class for vSphere API calls specific to a distributed virtual switch in a vCenter datacenter.
