[202012] Configure different map between uplink and downlink on t1 switch in dual ToR scenario (#11299)
- Why I did it
Configure different DSCP_TO_TC_MAP between uplink and downlink on T1 switch in dual ToR scenario
On T1 uplink, both DSCP 2/6 will be mapped to TC 1 for the purpose of avoiding such traffic occupying lossless buffers.
On T1 downlink, they will be mapped to TC 2/6 respectively. (unchanged)

- How I did it
For vendors who want to configure different DSCP_TO_TC_MAP between uplinks and downlinks on T1, they should
Define generate_dscp_to_tc_map macro in SKU's qos.json.j2 file
Define map AZURE for downlink and AZURE_UPLINK for uplink
Define jinja2 variable different_dscp_to_tc_map as True
