[why] friendly show compare template result in command line.

[how] rehandle the json format result of "compare -t <compare_template.yaml>" with third-party module in python3.

[usage] compare_template <compare_template.yaml>

[example] compare_template compare_template.yaml in z9

[input] a compare_template.yaml like below:

compare_metrics: - fio.write_iops - fio.read_iops filter: suite: - fio-basic os_arch: - aarch64 - x86 compare_dimensions: - os: debian os_version: sid - os: openeuler os_version: 20.03 x_params: - bs - test_size title: Hackbench Performance Testing unit: KB/s

[output]
