Create power supply redundancy and derating factor sensors

[geissonator]

Some details in #1213. Need to implement these using the new ipmid sensor design.

[geissonator]

Phase 5 for now, @spinler to check with occ team on impacts.

[dhruvibm]

• Add YAMLs for ps derating and redundancy

• Create an application for handling PS redundancy and derating

• Add IPMI sensor read support for new interfaces.

Made changes that are need for Phase 5. It is ready for merge review.
I would be completing 2220 first before moving on to this one.

[tomjoseph83]

We should be removing the Power Supply redundancy/Power derating & Turbo allowed(Power specific) from the legacy dbus path check, once we get these changes in.

Merged

Resolves #2154 Create power supply redundancy and derating factor sensors

[geissonator]

This was backed out, need to find story where we bring this back in.

[dkodihal]

@dhruvibm can you use this story to write new dbus interfaces and app for the PS sensors, along with ipmid changes?

[dhruvibm]

Status

Need to decide the application implementing the PS derating and redundancy servers.

[dkodihal]

This was implemented via https://gerrit.openbmc-project.xyz/#/q/topic:PowerSupplyRedundancy

[dkodihal]

It looks like there are still a bunch of sensors implemented via the legacy code path/python apps. @ngorugan and @tomjoseph83 will figure out which and will switch them over to the data-driven code.

[tomjoseph83]

There are 2 sensors that needs to be moved from legacy code to generated code.

a) Power Supply Redundancy is supported in the settings. So the input yaml for the sensor generation needs to be updated.

b) The implementation of power derating sensor needs to be discussed.

@tomjoseph83 @dkodihal What is this issue tracking now? Should it just be closed? We have a power supply redundancy sensor.
