[device/celestica]: Fix remaining failed test cases of Seastone-DX010 platform API (#7743)
**- Why I did it**
- To fix failed test cases of Seastone-DX010 platform APIs that found on [platform_tests](https://github.com/Azure/sonic-mgmt/tree/master/tests/platform_tests/api) script

**- How I did it**
1. Add device/celestica/x86_64-cel_seastone-r0/platform.json 
2. Update functions to support python3.7
3. Add more functions follow latest sonic_platform_base
4. Fix the bug
