Migrate the block storage aspects of this command to SDK. This means the
'extension list' command, like the 'availability zone list' command
previously, is now using SDK entirely.
While we're here, we also make some fixes to the unit tests for the
network and compute aspects of the command. While we migrated the
network and compute extension commands from neutronclient and novaclient
respectively some time back, we never fully updated the tests. Do this
now.
