Update the glanceclient CLI to support both underscores and dashes. Dashes are prefered and show up in help. This will hopefully keep the CLI more consistent with the other OpenStack client projects like Nova, Swift, Keystone in addition to the old Glance client which all seem to prefer underscores to dashes. Fixes LP Bug #1018467. Change-Id: I80d7a19f94033554f7f639166911726de4a5159f
