- Why I did it
Support zero buffer profiles
1. Add buffer profiles and pool definition for zero buffer profiles
2. Support applying zero profiles on INACTIVE PORTS
3. Enable dynamic buffer manager to load zero pools and profiles from a JSON file
- How I did it
Add buffer profiles and pool definition for zero buffer profiles
If the buffer model is static:
* Apply normal buffer profiles to admin-up ports
* Apply zero buffer profiles to admin-down ports
If the buffer model is dynamic:
* Apply normal buffer profiles to all ports
* buffer manager will take care when a port is shut down
Update buffers_config.j2 to support INACTIVE PORTS by extending the existing macros to generate the various buffer objects, including PGs, queues, ingress/egress profile lists
Originally, all the macros to generate the above buffer objects took active ports only as an argument.
Now that buffer items need to be generated on inactive ports as well, an extra argument representing the inactive ports need to be added.
To be backward compatible, a new series of macros are introduced to take both active and inactive ports as arguments
The original version (with active ports only) will be checked first. If it is not defined, then the extended version will be called.
Only vendors who support zero profiles need to change their buffer templates
Enable buffer manager to load zero pools and profiles from a JSON file:
The JSON file is provided on a per-platform basis
It is copied from platform/<vendor> folder to /usr/share/sonic/temlates folder in compiling time and rendered when the swss container is being created.
To make code clean and reduce redundant code, extract common macros from buffer_defaults_t{0,1}.j2 of all SKUs to two common files:
One in Mellanox-SN2700-D48C8 for single ingress pool mode
The other in ACS-MSN2700 for double ingress pool mode
Those files of all other SKUs will be symbol link to the above files
Update sonic-cfggen test accordingly:
* Adjust example output file of JSON template for unit test
* Add unit test in for Mellanox's new buffer templates.
- How to verify it
Regression test.
Unit test in sonic-cfggen
Run regression test and manually test.

- Why I did it
Wrong SKU configuration will lead to longer init flow.
This will affect fast-reboot feature by increasing the traffic downtime.
Since MLNX met the required downtime period with this SKU this bug found with a delay.
- How I did it
Add the required split labels for ports.
- How to verify it
Run fast-reboot with this platform using SN3800-D112C8 SKU.
- 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

#### 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.

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**
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
