Current "volume list --name" command use "display_name" as search_opts
to send to cinder API, and show the result table with "Display Name"
column title in osc, cinder list API support "name" as search opts too,
and there is "name" attribute in volume response body, so we can replace
all "Display Name" by "Name" in order to keep "volume list" command
consistent with other commands, like: server list, network list and so
on, only use "Name" attribute for all objects.
Support a mapping for volume list -c "Display Name" (Volume v1 and v2)
and volume create/show -c "display_name" (Volume v1) for minimal
backward compatibility until R release.
