This is to backport community PR 8768 to 202012 branch

  1. Add buffer profiles and pool definition for zero buffer profiles
    • If buffer model is static:
      • Apply normal buffer profiles to admin-up ports
      • Apply zero buffer profiles to admin-down ports
    • If buffer model is dynamic:
      • Apply normal buffer profiles to all ports
      • buffer manager will take care when a port is shutdown
  2. 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 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
  3. Adjust example output file of json template for unit test
