#### Why I did it
Currently, SONiC use a single value to represent SFP error, however, multiple SFP errors could exist at the same time. This PR is aimed to support it
#### How I did it
Return bitmap instead of single value when a SFP event occurs

- 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

#### Why I did it
According to thermalctld hld, each fan must belong to a fan drawer, if the fan drawer does not physically exist, put fan into a virtual fan drawer. This PR is to clear fan from chassis._fan_list
#### How I did it
1. Don't put fan to chassis._fan_list
2. Always query fan from fan_drawer
#### Why I did it
This pull request allows calls to be made through the platform 2.0 API that retrieve the PSU and Chassis hardware revision on Mellanox platforms. Access to these values will aid customers in determining their hardware revisions for debugging and technical support. These values are intended to be eventually exposed through the CLI.
#### How I did it
For the PSU hardware revision I used the existing VPD function calls implemented in https://github.com/Azure/sonic-buildimage/pull/7382
For the Chassis hardware revision I parsed the SMBIOS / DMI type 2 information to retrieve the information.
Originally, SFP modules were always accessed from platform daemons, and arbitrary SFP modules can be accessed in the daemon. So all SFP modules were initialized in one shot once one of the following chassis APIs called
- get_all_sfps
- get_sfp_numbers
- get_sfp
Recently, we noticed that SFP modules can also be accessed from CLI, eg. the latest refactor of `sfputil`.
In this case, only one SFP module is accessed in the chassis object's life cycle.
To initialize all SFP modules in one shot is waste of time and causes the CLI to take much more time to finish.
So we would like to optimize the initialization flow by introducing a two-phase initialization approach:
- Partial initialization, which means the `chassis._sfp_list` has been initialized with proper length and all elements being `None`
- Full initialization, which means all elements in `chassis._sfp_list` are created
If the relevant function is called,
- `get_sfp`, only partial initialization will be done, and then the specific SFP module is initialized.
- `get_all_sfps` or `get_num_sfps`, full initialization will be done, which means all SFP modules are initialized.

The following error message is observed during chassis object being destroyed
"Exception ignored in: <function Chassis.__del__ at 0x7fd22165cd08>
Traceback (most recent call last):
File "/usr/local/lib/python3.7/dist-packages/sonic_platform/chassis.py", line 83, in __del__
ImportError: sys.meta_path is None, Python is likely shutting down
The chassis tries to import deinitialize_sdk_handle during being destroyed for the purpose of releasing the sdk_handle.
However, importing another module during shutting down can cause the error because some of the fundamental infrastructures are no longer available."
This error occurs when a chassis object is created and then destroyed in the Python shell.
- How I did it
To fix it, record the deinitialize_sdk_handle in the chassis object when sdk_handle is being initialized and call the deinitialize handler when the chassis object is being destroyed
- How to verify it
Manually test.
- Why I did it
Add support for new 64x200G SN4600 systems
- How I did it
Add all relevant files (w/o platform.json and hwsku.json as they will come later) with default SKU.
- How to verify it
Install image on switch, verify all ports are up and configured properly, run full platform SONiC tests.
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
In order to support SONiC physical entity mib extension, a few new platform API are added to sonic-platform-common, this PR is to provide an mellanox platform implementation for those new APIs.
When detecting a new SFP insertion, read its SFP type and DOM capability from EEPROM again.
SFP object will be initialized to a certain type even if no SFP present. A case could be:
1. A SFP object is initialized to QSFP type by default when there is no SFP present
2. User insert a SFP with an adapter to this QSFP port
3. The SFP object fail to read EEPROM because it still treats itself as QSFP.
This PR fixes this issue.
The `get_serial_number()` method in the ChassisBase and ModuleBase classes was redundant, as the `get_serial()` method is inherited from the DeviceBase class. This method was removed from the base classes in sonic-platform-common and the submodule was updated in https://github.com/Azure/sonic-buildimage/pull/5625.
This PR aligns the existing vendor platform API implementations to remove the `get_serial_number()` methods and ensure the `get_serial()` methods are implemented, if they weren't previously.
Note that this PR does not modify the Dell platform API implementations, as this will be handled as part of https://github.com/Azure/sonic-buildimage/pull/5609
**- Why I did it**
- Platform API implementation using sonic-cfggen to get platform name and SKU name, which will fail when the database is not available.
- Chassis name is not correctly assigned, it shall be assigned with EEPROM TLV "Product Name", instead of SKU name
- Chassis model is not implemented, it shall be assigned with EEPROM TLV "Part Number"
**- How I did it**
1. Chassis
> - Get platform name from /host/machine.conf
> - Remove get SKU name with sonic-cfggen
> - Get Chassis name and model from EEPROM TLV "Product Name" and "Part Number"
> - Add function to return model
2. EEPROM
> - Add function to return product name and part number
3. Platform
> - Init EEPROM on the host side, so also can get the Chassis name model from EEPROM on the host side.
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 in https://github.com/Azure/sonic-buildimage/pull/5003
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 the next step toward resolving https://github.com/Azure/sonic-buildimage/issues/4999
Also reverted my previous change in which device_info.get_platform() would first try obtaining the platform ID string from Config DB and fall back to gathering it from machine.conf upon failure because this function is called by sonic-cfggen before the data is in the DB, in which case, the db_connect() call will hang indefinitely, which was not the behavior I expected. As of now, the function will always reference machine.conf.
System health feature needs to set/get system led status
- Add a led object in chassis class and initialize it when the API is called on host side
- Read/write system led system fs to get/set the status

Since the only hardware-causing reboot should be handled by get_reboot_cause and the logic of handling reboot cause is about to move to the host side, no need to mount this dir to pmon docker.
This reverts commit 3feb96869d.
2. adjust log output by using sonic_daemon_base.daemon_base.Logger.
3. remove the logic of verifying /host/reboot-cause/ files.
