feat(inputs.gnmi): Add option to create more descriptive tags

[srebhan]

Summary

While investigating an issue report I noticed that paths with multiple keys like

/openconfig-platform:components/component[name="LM-1"]/subcomponents/subcomponent[name="PORT-1-1"]/name

produce very bulky and undescriptive tags like /openconfig-platform:components/component/subcomponents/subcomponent/name=PORT-1-1,name=LM-1 because key-keys are usually named name.

The new prefix_tag_key_with_path would produce more descriptive tags component_name=LM-1,subcomponent_name=PORT-1-1 by prefixing the key with the path segment containing the key.

Thanks! Out of curiosity, do we need the full 28k line JSON file or could a more limited version be used?

Not necessarily. Should I shorten it?

Not necessarily. Should I shorten it?

If it isn't straight forward, then we can keep as-is.

@powersj shortened to ~1k lines...

Fantastic, thank you very much!
