replace metavar "volume-id" with "volume" to avoid ambiguity

Browse source 
The help message of command "openstack volume show" accepts either
volume-name or volume-ID. But the metavar is "volume-id" as below.
It can easily lead to misunderstanding.

usage: openstack volume show [-h] [-f {json,shell,table,value,yaml}]
                             [-c COLUMN] [--max-width <integer>]
                             [--noindent][--prefix PREFIX]
                             <volume-id>
