Support shared headroom pool for Microsoft SKUs (#6366)

- Why I did it Support shared headroom pool Signed-off-by: Stephen Sun [email protected] - How I did it Port configurations for SKUs based on 2700/3800 platform from 201911 For SN3800 platform: C64: 32 100G down links and 32 100G up links. D112C8: 112 50G down links and 8 100G up links. D24C52: 24 50G down links, 20 100G down links, and 32 100G up links. D28C50: 28 50G down links, 18 100G down links, and 32 100G up links. For SN2700 platform: D48C8: 48 50G down links and 8 100G up links C32: 16 100G downlinks and 16 100G uplinks Add configuration for Mellanox-SN4600C-D112C8 112 50G down links and 8 100G up links. - How to verify it Run regression test.
