[Compass-ci] Re: [PATCH compass-ci 1/2] user-client/maintain: test os rootfs in z9 tbox

TO ALL For tools/scripts, let's add help message to show - description on usage, purpose, scenario etc. - command line params - input/output - example

+ message = %x(submit -s 'os: #{os}' -s 'os_arch: #{os_arch}' -s 'os_version: #{os_version}' -s 'os_mount: #{os_mount}' iperf-walk-os.yaml)

The '=' form looks more simple than '-s': os=#{os} ... Thanks, Fengguang
