Add support for test_power_off_reboot for Cisco 8808 chassis (#16736)

Description of PR
Add support for test_power_off_reboot for Cisco 8808 chassis. For chassis, till we can add calculation to find minimum number of PSU up based on the load of the system, we will bringup all the PSU before we continue the test.

Summary:
Fixes # (issue)

Approach
What is the motivation for this PR?
Add support for test_power_off_reboot for Cisco 8808 chassis. For chassis, till we can add calculation to find minimum number of PSU up based on the load of the system, we will bringup all the PSU before we continue the test.

How did you do it?
How did you verify/test it?
On T2 profiles

Any platform specific information?
Cisco 8808 chassis

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