[snappi][2405] - 'get_egress_queue_count' should use CLI - show queue counter -n asic0 - to capture queue stats

[amitpawar12]

Issue Description

In 2405, the 'sudo ip netns exec asic0 show queue counter' is being used in 'get_egress_queue_count' function to capture the egress queue count.

This CLI was good for 2205 as there was no support for ASIC in 'show queue counter' then. But in 2405, the CLI has support for '-n asic0' flag and hence should be used.

Affected functions/testcases:
get_egress_queue_count is being called following functions:

1. tests/bfd/test_bfd.py
2. run_traffic function in traffic_generation.py. This function creates dictionary, which is then also used by verify_egress_queue_frame_count. PFC testcases calls 'verify_egress_queue_frame_count' to ensure that no packets are sent out of DUT when egress port is stormed.

Results you see

The old CLI (with sudo ip netns exec) is/was workaround to capture statistics in multi-asic environment. However, with '-n asic0' flag available in show queue counter CLI, we should modify the function to use the above CLI in 2405 environment.

Results you expected to see

New CLI. The functionality, way to parse results and format of result (dictionary) should not change.

@auspham to work on this.

we have to check if this will be backward-compatible with 2205

Confirmed that 2205 support this sonic-net/sonic-utilities#2439
