Summary

Platform manager has a versionedPmUnitConfigs attribute, which allows certain pmUnit configs to be overridden. However, it is only limited to changes "Product Sub-Version".

This proposal adds support for all 3 version attributes in meta-eeprom to be used in versionedPmUnitConfigs. To do that, the PmUnitVersion struct is used as suggested by the TODO comment in the thrift config.

Test Plan

• All Swtests pass

Manual Testing of The Feature

We will be working with these set of versions on the SMB pmunit

...
Product Production State: 1
Product Version: 2
Product Sub-Version: 3
...

No versionedPmUnitConfigs present

...

...

Testing versionedPmUnitConfigs with a duplicated SMB pmunit but removing SMB_CPLD. Setting productSubVersion set to 2 (NOT MATCHING).
