- Why I did it
For CMIS host management module, we need a different implementation for sfp.reset. This PR is to implement it
- How I did it
For SW control modules, do reset from hw_reset
For FW control modules, do reset as the original way
- How to verify it
Manual test
sonic-mgmt platform test
- Why I did it
New implementation of Nvidia platform_wait due to:
1. sysfs deprecated by hw-mgmt
2. new dependencies to SDK
3. For CMIS host management mode
- How I did it
wait hw-management ready
wait SDK sysfs nodes ready
- How to verify it
manual test
unit test
sonic-mgmt regression
- Why I did it
When module is totally under software control, driver cannot get module temperature/temperature threshold from firmware. In this case, sonic needs to get temperature/temperature threshold from EEPROM. In this PR, a thread thermal updater is created to update module temperature/temperature threshold while software control is enabled.
- How I did it
Query ASIC temperature from SDK sysfs and update hw-management-tc periodically
Query Module temperature from EEPROM and update hw-management-tc periodically
- How to verify it
Manual test
New Unit tests
- Why I did it
Provide a dummy implementation for SFP error description when CMIS host management is enabled. A future feature shall be raised to implement SFP error description for such mode.
- How I did it
if SFP is under software control, provide "Not supported" as error description
if SFP is under initialization, provide "Initializing" as error description
- How to verify it
unit test
- Why I did it
On Mellanox platform, system EEPROM is a soft link provided by hw-management. There is chance that config-setup service accessing the EEPROM before hw-management creating it. It causes errors. The PR is aim to fix it.
- How I did it
Waiting EEPROM creation in platform API up to 10 seconds.
- How to verify it
Manual test
- Why I did it
Following code to judge whether a process is running inside a docker could get stuck on the simx platform
subprocess.Popen(["docker", "--version"],
stdout=subprocess.PIPE,
stderr=subprocess.STDOUT,
universal_newlines=True)
When it gets stuck, the config-chassisdb service can not be successfully started, thus the system can not be booted up.

- How I did it
Use an alternative way to implement this function and issue can be avoided:
docker_env_file = '/.dockerenv'
return os.path.exists(docker_env_file) is False

run regression on real hardware and simx platform.

Dependency: [PR (#12065)](https://github.com/sonic-net/sonic-buildimage/pull/12065) needs to merge first.
#### Why I did it
`subprocess.Popen()` and `subprocess.check_output()` is used with `shell=True`, which is very dangerous for shell injection.
#### How I did it
Disable `shell=True`, enable `shell=False`
#### How to verify it
Tested on DUT, compare and verify the output between the original behavior and the new changes' behavior.

- Why I did it
There is a hardware bug that PSU voltage threshold sysfs returns incorrect value. The workaround is to call "sensor -s" to refresh it.
- How I did it
Call "sensor -s" when the threshold value is not incorrect and PSU is "DELTA 1100"

#### Why I did it
Recently, CLI sfputil replace the old sonic platform utils with sonic platform API. However, sonic platform API does not support SFP low power mode and reset related operation. The PR is to fix it.
The change to replace platform utils with sonic platform API was reverted on 202012, once this PR is merged, we can cherry-pick these two PRs to 202012 together.
#### How I did it
In low power mode and reset related operation, use "docker exec" if the command is running on host side.
