- Why I did it
To create SDK dump on Mellanox devices when SDK event has occurred.
- How I did it
Set the SKUs keys needed to initialize the feature in SAI.
- How to verify it
Simulate SDK event and check that dump is created in the expected path.
- Why I did it
This is to back-port Azure 7410 to 202012 branch.
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
Run regression test
#### Why I did it
The label for PSU related sensors on the Spectrum-2 platform is not aligned with the physical location of the PSU.
#### How I did it
Update the label in the sensor conf file for those relevant platforms

#### Why I did it
MSN4700 A1/A0 used different sensor chip but keep the existing platform name *x86_64-mlnx_msn4700-r0*, this is a workaround to replace the sensor conf on MSN4700 A1/A0
#### How I did it
Use a shell script to get the sensor conf path and copy that files to /etc/sensors.d/sensors.conf
- Why I did it
Current platform.json lacks some peripheral device related facts, like chassis/fan/pasu/drawer/thermal/components names, numbers, etc.
- How I did it
Add platform device facts to the platform.json file
- How to verify it
Run sonic-mgmt platform API tests which depend on these facts.

Fix to the correct value for all SPC1 devices.
For 10G added 10GB_CX4_XAUI, 10GB_KX4, 10GB_KR, 10GB_SR and 10GB_ER_LR
For 50G added 50GB_SR2
This bitmask represents all the options available for interface type and some were missing.
Note: it was working just fine if you were setting the value from SONiC CLI but not from the default SAI Profile.

The file device/mellanox/x86_64-mlnx_msn4410-r0/plugins/sfputil.py is not a software link for device/mellanox/x86_64-mlnx_msn2700-r0/plugins/sfputil.py. And it is still using python2 syntex which causes some SFP CLI error. The PR is to change it to a softlink and add 4410 support in device/mellanox/x86_64-mlnx_msn2700-r0/plugins/sfputil.py.
- Why I did it
Mellanox-SN4600C-D112C8 SKU is not configured properly.
It should have 112 50G interfaces and 8 100G interfaces as described on this PR.
- How I did it
Changed port_config.ini & sai profile.
- How to verify it
Apply this HwSKU to a MSN4600C Mellanox platform.
#### Why I did it
Change buffer config for new SKU Mellanox-SN2700-D40C8S8
#### How I did it
Reuse the buffer config of SKU Mellanox-SN2700-D48C8
#### How to verify it
Run sonic-mgmt qos test and all passed
- Why I did it
To fix PCIEd errors in log.
- How I did it
Update pcie.yaml with the right PCI addresses.

- 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.
#### Why I did it
Add new SKU for SN2700 Mellanox system that supports the following port configuration:
8 X 100G
40 X 50G
8 X 10G
#### How I did it
Add new Folder - "Mellanox-SN2700-D40C8S8" under /sonic-buildimage/device/mellanox/x86_64-mlnx_msn2700-r0/
that contains the relevant files supporting this SKU
the buffers are based on SKU: D48C8 . Later on it will be configured specific for this SKU
#### How to verify it
Bring up the image, run "show interface status" and make sure that all ports are up and reflect the following requirement:
Port 1/3 will be used as 4x10G
Port 2/4 - Not exist (blocked since 1 and 3 split to 4)
Port 7/8/9/10/23/24/25/26 will used as 100G
All other ports will be used as 2x50G

**- 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.
In order to build up device hierachy, PSU and module thermals are no longer child of chassis. PSU thermal belongs to PSU objects and SFP thermals belong to SFP object now. Need align this change in platform.json. Move thermal objects to correct parent device
**- Why I did it**
To support dynamic buffer calculation.
This PR also depends on the following PRs for sub modules
- [sonic-swss: [buffermgr/bufferorch] Support dynamic buffer calculation #1338](https://github.com/Azure/sonic-swss/pull/1338)
- [sonic-swss-common: Dynamic buffer calculation #361](https://github.com/Azure/sonic-swss-common/pull/361)
- [sonic-utilities: Support dynamic buffer calculation #973](https://github.com/Azure/sonic-utilities/pull/973)
**- How I did it**
1. Introduce field `buffer_model` in `DEVICE_METADATA|localhost` to represent which buffer model is running in the system currently:
- `dynamic` for the dynamic buffer calculation model
- `traditional` for the traditional model in which the `pg_profile_lookup.ini` is used
2. Add the tables required for the feature:
- ASIC_TABLE in platform/\<vendor\>/asic_table.j2
- PERIPHERAL_TABLE in platform/\<vendor\>/peripheral_table.j2
- PORT_PERIPHERAL_TABLE on a per-platform basis in device/\<vendor\>/\<platform\>/port_peripheral_config.j2 for each platform with gearbox installed.
- DEFAULT_LOSSLESS_BUFFER_PARAMETER and LOSSLESS_TRAFFIC_PATTERN in files/build_templates/buffers_config.j2
- Add lossless PGs (3-4) for each port in files/build_templates/buffers_config.j2
3. Copy the newly introduced j2 files into the image and rendering them when the system starts
4. Update the CLI options for buffermgrd so that it can start with dynamic mode
5. Fetches the ASIC vendor name in orchagent:
- fetch the vendor name when creates the docker and pass it as a docker environment variable
- `buffermgrd` can use this passed-in variable
6. Clear buffer related tables from STATE_DB when swss docker starts
7. Update the src/sonic-config-engine/tests/sample_output/buffers-dell6100.json according to the buffer_config.j2
8. Remove buffer pool sizes for ingress pools and egress_lossy_pool
Update the buffer settings for dynamic buffer calculation
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
