[DOCS][AWP] New page for Kubernetes dashboard

[benironside]

Fixes #2213 by creating a new page in the Dashboards section of docs that describes how to set up and understand the Kubernetes dashboard.

Also fixes #2214 by updating the Session View doc to mention K8s data.

Previews:

• Kubernetes dashboard
• Session view

This is awesome! Thank you @benironside

We are wondering if it's worth mentioning in this doc that the data source used in the kubernetes dashboard is the logs pattern of the securitySolution:defaultIndex from advanced settings, which is configurable and is used by the rest of security solution pages.

This is useful when users have a cross cluster set up, where they will need to change the default logs-* pattern to something like *:logs-* to see data across several clusters.

An alternative suggested by Glo is that we can mention it in the release note.

Hi Team,

This feature is not taken care by our team, so we are not the right person to review the Doc.

Thanks!
