Change PSU key to use get_name API instead of index

Change PSU key to use get_name API instead of index

Description

Changes PSU keys to be implemented via their get_name API like we do for fans instead of simple indexing. If the get_name API is not implemented by vendors then will fall back to the original indexing schema.

Motivation and Context

Makes PSU objects more clear in context by attaching their associated get_name to their PSU key similar to how it is done for fan objects.

How Has This Been Tested?

Along with other modifications in other repos, this is passing mgmt related test cases such as snmp tests and psu api tests. Additionally, can verify the output via psushow script.

@gregoryboudreau useful addition. Couple questions:

If the get_name API is not implemented by vendors then will fall back to the original indexing schema.
Has this been tested?

Additionally, please fix unit test failures that appear to be indexing related. Thanks!

@gregoryboudreau can you please run sonic-mgmt test cases for PSU with all the changes. Attach the result to this PR?

Let me know if there are other test cases that I missed in running, thanks!

@assrinivasan with the get_name API implemented:

root@mth64-m5-2:/home/cisco# show platform psustatus
PSU    Model         Serial         HW Rev  Voltage (V)    Current (A)    Power (W)    Status    LED
-----  ------------  -----------  --------  -------------  -------------  -----------  --------  -----
PSU0   PSU650W-ACPE  LIT241955UQ      0.00  11.996         24.0           288.0        OK        green
PSU1   PSU650W-ACPE  LIT241956QK      0.00  N/A            N/A            N/A          NOT OK    off

This is with the get_name API overwritten to raise NotImplemented for PSUs:

root@mth64-m5-2:/home/cisco# show plat psu
PSU    Model         Serial         HW Rev  Voltage (V)    Current (A)    Power (W)    Status    LED
-----  ------------  -----------  --------  -------------  -------------  -----------  --------  -----
PSU 1  PSU650W-ACPE  LIT241955UQ      0.00  11.98          24.0           288.0        OK        green
PSU 2  PSU650W-ACPE  LIT241956QK      0.00  N/A            N/A            N/A          NOT OK    off

The only functional difference between the two is the key/naming
