Backport #14372 to 202205
Why I did it
For better accounting purposes, updating the ingress lossy traffic profile to use static threshold. This change is only intended for Th devices using RDMA-CENTRIC profiles
How I did it
Update the buffer templates for Th devices in RDMA-CENTRIC folder to use the correct threshold

Why I did it
Update dynamic threshold to -1 to get optimal performance for RDMA traffic
How I did it
Modified pg_profile_lookup.ini to reflect the correct value

Why I did it
ECN parameters need to be updated for storage backend
How I did it
Included the check for storage backend devices to update qos configs
How to verify it
Verified that the new ecn settings are applied on storage backend device.
Verified that the old ecn settings are applied for storage frontend, non storage frontend/backend devices
Why I did it
The PR is to apply separated DSCP_TO_TC_MAP and TC_TO_QUEUE_MAP to uplink ports on dualtor.
The traffic with DSCP 2 and DSCP 6 from T1 is treated as lossless traffic.
DSCP TC Queue
2 2 2
6 6 6
Traffic with DSCP 2 or DSCP 6 from downlink is still treated as lossy traffic as before.
How I did it
Define DSCP_TO_TC_MAP|AZURE_UPLINK and TC_TO_QUEUE_MAP|AZURE_UPLINK.
How to verify it
Verified by UT
Verified by coping the new template to a testbed, and rendering a config_db.json

Why I did it
There is a need to have separate profiles on compute and storage and this infra update will help achieve that
How I did it
Moved buffer pool/profile and qos definitions on TD2 to a common folder and all TD2 hwsku's will reference that folder
Why I did it
This PR is to update TC_TO_QUEUE_MAP|AZURE for SKU Arista-7050CX3-32S-D48C8 and Arista-7260CX3 T0.
The change is only to align the TC_TO_QUEUE_MAP for regular traffic and bounced traffic. It has no impact on business because we have no traffic being mapped to TC2 or TC6.
How I did it
Update TC_TO_QUEUE_MAP|AZURE , and test cases as well.
How to verify it
Verified by running test case test_j2files.py
/sonic/src/sonic-config-engine$ python3 setup.py test -s tests/test_j2files.py
running test

Why I did it
Improve throughput and latency for 7260 deployments
How I did it
Update the dynamic threshold to 0 and ECN settings as 2mb/10mb/5%
How to verify it
Updated unit tests to use the modified values for 7260 ecn settings.
