Why I did it
The Mellanox platform is required to support the fwutil auto-update feature defined here
This is to allow switches, when performing SONiC upgrades to choose whether to perform firmware upgrades that may interrupt the data plane through a cold boot.
How I did it
Two methods were added to the component implementations for mellanox.
In the base Component class we add a default function that chooses to skip the installation of any firmware unless the cold boot option is provided. This is because the Mellanox platform, by default, does not support installing firmware on ONIE, the CPLD, or the BIOS "on-the-fly".
In the ComponentSSD class we add a function that behaves similarly but uses the Mellanox specific SSD firmware upgrade tool to check if the current SSD supports being upgraded on the fly in order to decide whether to skip or perform the installation.
How to verify it
Unit tests are included with this PR. These test will run on build of target sonic-mellanox.bin
You may also perform fwutil auto-update ... commands after Azure/sonic-utilities#1242 is merged in.
- Why I did it
Enhance the Python3 support for platform API. Originally, some platform APIs call SDK API which didn't support Python 3. Now the Python 3 APIs have been supported in SDK 4.4.3XXX, Python3 is completely supported by platform API
- How I did it
Start all platform daemons from python3
1. Remove #/usr/bin/env python at the beginning of each platform API file as the platform API won't be started as daemons but be imported from other daemons.
2. Adjust SDK API calls accordingly
- How to verify it
Manually test and run regression platform test

In preparation for the merging of Azure/sonic-platform-common#173, which properly defines class and instance members in the Platform API base classes.
It is proper object-oriented methodology to call the base class initializer, even if it is only the default initializer. This also future-proofs the potential addition of custom initializers in the base classes down the road.
python2 is end of life and SONiC is going to support python3. This PR is going to support:
1. Mellanox SONiC platform API python3 support
2. Install both python2 and python3 verson of Mellanox SONiC platform API or pmon and host side
*Currently get_firmware_version implementated by using chassis.get_firmware_version and chassis._component_name_list which are not supported in the latest sonic_platform_common, causing chassis broken. Update this part so that it aligns to the latest sonic_platform_common
*Support component API
