[k8s] Stabilize k8s resource/entity attributes

[ChrsMark]

Part of #3119.

This issue suggests that we stabilise all resource/entity attributes that are used by the following Collector components:

• k8sattributes processor (from metadata.yaml and extract::metadata)
• resourcedetection processor
• filelog receiver

Related to open-telemetry/opentelemetry-collector-contrib#44130.

Suggested Semantic Conventions

'✅' indicates that the Collector component makes use of this attribute
'🚫 ' indicates that the Collector component does not make use of this attribute

What does '🚫' mean on the resourcedetection processor?

I chose ✅ to indicate if the attribute is used by the components and 🚫, if it's not. Seeing this again it might not be the most obvious choice?

Ah, I guess I assume an empty cell was "not being used" but I suppose it means "not filled in yet" 😅
