[Compass-ci] TODO: multi-field matrix expansion in job.yaml

+TEST_OS = [

• 'openeuler aarch64 20.03',
• 'centos aarch64 7.6.1810',
• 'centos aarch64 7.8.2003',
• 'centos aarch64 8.1.1911', 'debian aarch64 sid'

Jihui, I wonder if we can support more general 'multi-field' matrix expansion logic in job.yaml, like this

os os_arch os_version: - openeuler aarch64 20.03 - centos aarch64 7.6.1810 - centos aarch64 7.8.2003

which will be split to 3 atom jobs with

os: openeuler os_arch: aarch64 os_version: 20.03

os: centos os_arch: aarch64 os_version: 7.6.1810

os: centos os_arch: aarch64 os_version: 7.8.2003

Thanks, Fengguang
