[SVf] Resize of GMCV volumes in group
[Spectrum Virtualize family] Currently, SVf does not support extend operation for GMCV volumes which are a part of a consistency group(CG). Added necessary code changes to storwize cinder driver to support this operation. Closes-Bug: #1960314 Change-Id: I9e9dd4f81582ec0d60b64c281f47bd48e907d0ea
