- Why I did it
Optimize thermal control policies to simplify the logic and add more protection code in policies to make sure it works even if kernel algorithm does not work.
- How I did it
Reduce unused thermal policies
Add timely ASIC temperature check in thermal policy to make sure ASIC temperature and fan speed is coordinated
Minimum allowed fan speed now is calculated by max of the expected fan speed among all policies
Move some logic from fan.py to thermal.py to make it more readable
- How to verify it
1. Manual test
2. Regression
As part of consolidating all common Python-based functionality into the new sonic-py-common package, this pull request:
1. Redirects all Python applications/scripts in sonic-buildimage repo which previously imported sonic_device_util or sonic_daemon_base to instead import sonic-py-common, which was added to the 201911 branch in https://github.com/Azure/sonic-buildimage/pull/5063
2. Replaces all calls to `sonic_device_util.get_platform_info()` to instead call `sonic_py_common.get_platform()` and removes any calls to `sonic_device_util.get_machine_info()` which are no longer necessary (i.e., those which were only used to pass the results to `sonic_device_util.get_platform_info()`.
3. Removes unused imports to the now-deprecated sonic-daemon-base package and sonic_device_util.py module
This is a step toward resolving https://github.com/Azure/sonic-buildimage/issues/4999

* support new platform api, thermal and psu part
for psu, all APIs are supported.
for thermal, we support
get_temperature,
get_high_threshold
for the thermal sensors of cpu core, cpu pack, psu and sfp module
and get_temperature for the ambient thermal sensors around the asic, port, fan, comex and board.
* 1. address review comments
2. improve the handling of PSU inserting/removal
3. tolerance diverse psu thermal sensor file name conventions
* 1. adjust thermal code according to the latest version of hw-management
2. check power_good_status rather than whether file existing ahead of reading voltage, current and power of PSU
