Support SMI-S provider v8.0.3 in VMAX driver

Support SMI-S provider v8.0.3 in VMAX driver

This patch made changes in the VMAX driver to support
interface changes in SMI-S provider v8.0.3.

* Accommodate System Name prefix change from 'SYMMETRIX+' to
  'SYMMETRIX-+-'.
* Delete composite volume - changed from using
  ReturnElementsToStoragePool to EMCReturnToStoragePool.
* Extend volume - removed InPool parameter from EMCUnBindElements
  method.
* Create snapshot/clone with multi meta members -
  EMC_PartialAllocOfConcreteExtentCIM was deprecated;
  used 'GetCompositeElements' instead and changed how we get meta
  members' capacities.
* Create CG snapshot - A new WaitForCopyState parameter was added.
* Added helper function to determine SMI-S provider and SE version
  Note: SMI-S provider is bundled with SE (Solutions Enabler) and
  they have the same version number starting from v8.0.
  The EMC SMI-S Provider supports the SNIA Storage Management Initiative
  (SMI), an ANSI standard for storage management. It supports the VMAX
  storage system. SE is a software product that discovers and manages
  VMAX storage system.
