    Replace "Display Name" by "Name" in volume list

    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.
