Dynamic Port Breakout fall in case "autoneg" field exist in config_db.
- How I did it
Added "autoneg" field in sonic-port yang model.
- How to verify it
Add "autoneg" field into config_db like this:
"Ethernet8": {
"index": "2",
"lanes": "8,9,10,11",
"fec": "rs",
"pfc_asym": "off",
"mtu": "9100",
"alias": "Ethernet8",
"admin_status": "up",
"autoneg": "on",
"speed": "100000",
},
#### Why I did it
- The xcvrd service requires an event detection function, unplug or plug in the transceiver.
#### How I did it
- Add sysfs interrupt to notify userspace app of external interrupt
- Implement get_change_event() in chassis api.
- Also begin installing Python 3 sonic-platform package for Celestica platforms
To fix [DPB| wrong aliases for interfaces](https://github.com/Azure/sonic-buildimage/issues/6024) issue, implimented flexible alias support [design doc](https://github.com/Azure/SONiC/pull/749)
> [[dpb|config] Fix the validation logic of breakout mode](https://github.com/Azure/sonic-utilities/pull/1440) depends on this
#### How I did it
1. Removed `"alias_at_lanes"` from port-configuration file(i.e. platfrom.json)
2. Added dictionary to "breakout_modes" values. This defines the breakout modes available on the platform for this parent port, and it maps to the alias list. The alias list presents the alias names for individual ports in order under this breakout mode.
```
{
"interfaces": {
"Ethernet0": {
"index": "1,1,1,1",
"lanes": "0,1,2,3",
"breakout_modes": {
"1x100G[40G]": ["Eth1"],
"2x50G": ["Eth1/1", "Eth1/2"],
"4x25G[10G]": ["Eth1/1", "Eth1/2", "Eth1/3", "Eth1/4"],
"2x25G(2)+1x50G(2)": ["Eth1/1", "Eth1/2", "Eth1/3"],
"1x50G(2)+2x25G(2)": ["Eth1/1", "Eth1/2", "Eth1/3"]
}
}
}
```
#### How to verify it
`config interface breakout`

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.
- Why I did it
The pcie configuration file location is under plugin directory not under platform directory.
#6437
- How I did it
Move all pcie.yaml configuration file from plugin to platform directory.
Remove unnecessary timer to start pcie-check.service
Move pcie-check.service to sonic-host-services

**- Why I did it**
PR https://github.com/Azure/sonic-platform-common/pull/102 modified the name of the SFF-8436 (QSFP) method to align the method name between all drivers, renaming it from `parse_qsfp_dom_capability` to `parse_dom_capability`. Once the submodule was updated, the callers using the old nomenclature broke. This PR updates all callers to use the new naming convention.
**- How I did it**
Update the name of the function globally for all calls into the SFF-8436 driver.
Note that the QSFP-DD driver still uses the old nomenclature and should be modified similarly. I will open a PR to handle this separately.
BRCM SDK 6.5.21 includes firmware updates (premier cancun) for TD3 platforms. The firmware update is required on TD3 platforms, which is packaged with BCMSAI 4.3.0.10.
**- How I did it**
Updated BCM config with a new variable that specifies the firmware package path. SDK uses this path to locate firmware packages and load during cold boot.

**- Why I did it**
- The thermalctld daemon on the Pmon docker requires support from the thermal manager API.
**- How I did it**
- Removed the old function for detecting a faulty fan.
- Removed the old function for detecting excess temperature.
- Implement thermal_manager APIs based on ThermalManagerBase
- Implement thermal_conditions APIs based on ThermalPolicyConditionBase

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

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.
