[Bug]: platform_tests/test_power_off_reboot.py needs to be updated for T2

[Javier-Tan]

Issue Description

Running platform_tests/test_power_off_reboot.py on a T2 device typically fails. Here are the reasons why:

• Checks if all outlets are providing power
  • In a T2 device sometimes 2 PDUs provide power to 1 PSU for redundancy, sometimes one PDU is dormant (purely for redundancy) while another is active, the test will fail in this case
• reboot_and_check command is missing relatively new duthosts kwarg that is used when running on sup card

There is also a related issue #16289 that occurs on T2 devices after fixing these 2 issues.
