Description of PR

Summary:
Fixes # (issue)#13769

Type of change

• Bug fix
• Testbed and Framework(new/improvement)
• New Test case
  • Skipped for non-supported platforms
• Test case improvement

Back port request

• 202205
• 202305

Approach

What is the motivation for this PR?

To support infra changes in snappi tests introduced by this Pull Request - #15069

How did you do it?

We don't need the setup_ports_and_dut now and we can simply call the snappi_testbed_config in the test itself and iterate through the available ports.

How did you verify/test it?

Any platform specific information?

Supported testbed topology if it's a new test case?
