[Kubernetes Integration] Updating kubernetes volume dashboard

[gizas]

• Enhancement

Proposed commit message

• WHAT: Updating the Kubernetes Volume Dashboard to include Volume information per Pod
• WHY: Adding more meaningful information because until now we were providing only general information for the volumes

Notes:

• Volume % : Defined as Maximum value
• A filter datastream.dataset=kubernetes.volume added in the visualisation

Checklist

• I have verified that all data streams collect metrics or logs.
• I have added an entry to my package's changelog.yml file.
• I have verified that Kibana version constraints are current according to guidelines.

This is not supposed to be here. How did you generate the panel?

@gizas there is smth wrong:
before this PR - there were 2 vizualisations:

after - 3 with wrong formating, one of them is a duplication:

[tetianakravchenko]

after clarification:

1. please add a title for the new vizualisation - like Volume usage [Metrics Kubernetes] (similar to other names)
2. clarify if pod name should be added to the Filesystem Inodes Informations [Metrics Kubernetes] and Filesystem Informations [Metrics Kubernetes] vizualisations as well

[gizas]

@eedugon lets clarify above questions: #10267 (comment)
For me the Filesystem Innformation related Visulaisations are general and should remain like that and the first visualisation for pods is enough to have the categories you want. WDYT?

I have added title Volume Usage per Pod[Metrics Kubernetes]

[tetianakravchenko]

LGTM!
Please clarify #10267 (comment) before merging.

Synced with @eedugon offline. There was a comment to change the filter of visualisation to metricset.name but we decide not. Reason was to keep it aligned as per other dashboards that have data_stream.dataset used.

This dashboard might need another update when the type of volume will be intorduced
