Description of PR Fix acl/test_stress_acl.py using bad interface name for ACL table creation Summary: Fixes # (issue) In acl/test_stress_acl.py, it attempts to retrieve an interface that can be used to create a ACL table. DUTs with and without PortChannels require different methods respectively. Currently, it checks by filtering with topo. However, some topology flags can have configurations that have or not have PortChannels, making topos no longer a sufficient check - in some topos the test will fail with: Error: Failed to parse ACL table config: exception=Cannot bind ACL to specified port Ethernet136 Reproducible by manually running the following on the DUT: config acl add table DATAACL L3 -s ingress -p Ethernet0 ^FAILS config acl add table DATAACL L3 -s ingress -p PortChannel101 ^WORKS

Approach
What is the motivation for this PR?
How did you do it?
Fix by checking if a PortChannel exists. If it does - use it. If it does not - fallback on the secondary method to retrieve a normal interface name if its a not a dualtor topo (due to
#6960).
How did you verify/test it?
Test no longer fails creating an ACL table on a t1 topo with PortChannels.
Tested with Arista HwSkus on t0, t1, t2, and mx topologies.
Any platform specific information?
Supported testbed topology if it's a new test case?
