Adding support for 'source-id' in 3PAR manage

Changed 3PAR's manage volume functionality to support the use of a
'source-id' id-type.  By default the name of the volume to manage can
be used but if an admin wants to use the volume ID instead they can
set the optional --id-type argument to 'source-id' now.
