Why I did it
Add the create_only_config_db_buffers attribute to the DEVICE_METADATA|localhost. If the "create_only_config_db_buffers" exists and is equal to "true" - the buffers will be created according to the config_db configuration (for example BUFFER_QUEUE|* table), otherwise the maximum available buffers (which are read from SAI) will be created, regardless of the CONFIG_DB buffers configuration.
Work item tracking
Microsoft ADO (number only):
How I did it
Add the create_only_config_db_buffers.json files for Mellanox devices (not MSFT SKU's), and inject the content to the CONFIG_DB during the swss docker container start.
How to verify it
Manual verification:
Install the image with this PR included on the not MSFT SKU switch
Check the show queue counters output and verify that only configured in CONFIG_DB buffers are created
root@sonic:/home/admin# show queue counters
Port TxQ Counter/pkts Counter/bytes Drop/pkts Drop/bytes

Open the /usr/share/sonic/device/$DEVICE/$SKU/create_only_config_db_buffers.json and change it to:
"create_only_config_db_buffers": "false"
