Support single ingress pool for MSFT SKUs and optimize headroom calculation (#5194)
This is to backport the #4886 to 201911

Calculate pool size in t1 as 24 * downlink port + 8 * uplink port

- Take both port and peer MTU into account when calculating headroom
- Worst case factor is decreased to 50%
- Mellanox-SN2700-C28D8 t0, assume 48 * 50G/5m + 8 * 100G/40m ports
- Mellanox-SN2700 (C32)
  - t0: 16 * 100G/5m + 16 * 100G/40m
  - t1: 16 * 100G/40m + 16 * 100G/300m
