Validate that the parent components of an entity is correct before and after reboot

• Verify parent component of an interface is a Switch Chip
• [TODO]: Add parent component verification for other hardware entities

• https://github.com/openconfig/featureprofiles/blob/main/topologies/atedut_2.testbed

• Connect ATE port-1 to DUT port-1, and ATE port-2 to DUT port-2

• Validate that the correct parent component "SwitchChip" is reported for DUT port1 and port2
• Reboot the DUT and verify the DUT finished rebooting by checking the uptime
• Re-validate that the correct parent component "SwitchChip" is reported for DUT port1 and port2
