[PATCH v6 compass-ci 3/3] kernel_version.md: explain key "kernel_version"
[why] Explain the meaning of new key "kernel_version" for scheduler, including what's the mapping between its typical values and actual files in the disk and how to set it.

The above example looks a bit complex.

+Usage example: +- submit iperf.yaml testbox=vm-hi1620-2p8g--xxj os=openeuler os_arch=aarch64 os_version=20.03 runtime=20 kernel_version=4.19.90-2003
That example cannot be run by others (testbox too specific). Do you have a more general example? Thanks, Fengguang
