[DX010 platform] fix dx010 platform testcase issues (#13595)
Why I did it
1. fix chassis test_set_fans_led case
2. fix chassis get_name case mismatch issue
3. fix fan_drawer test_set_fans_speed
4. fix component test_components test case

How I did it
Add corresponding configuration into chassis json file

How to verify it
Run platform tests cases to verify these failure cases
