Dynamic Plugin Template for custom metrics dashboard

1. Proposed title of this feature request
Dynamic Plugin Template for custom metrics dashboard

2. What is the nature and description of the request?
With OpenShift Container Platform 4.10, Dynamic Plugins went Tech Preview (https://docs.openshift.com/container-platform/4.10/release_notes/ocp-4-10-release-notes.html#ocp-4-10-dynamic-plugin-technology-preview) allowing to customize the web-console according to needs are requirements.

This is nice but requires a lot of effort on the customer to create such a plugin. It therefore would be nice to provide certain templates for such dynamic templates in order to help customers to get started. The templates could be for certain common use cases such as a page that allows viewing customer specific metric dashboards.

Similar what is available in the OpenShift 4 - Console under Observe with the dashboards but the ability to specify queries based on customer specific metrics and then define the type of the graph.

With the given template, it would be easier for customers to start adopting that functionality and continue building additional functionality if and where needed.

3. Why does the customer need this? (List the business requirements here)
Dynamic Plugins is great but requires some effort to get started if somebody is not super familiar with the SDK made available. Therefore providing templates for certain use cases would be helpful for customers and even partners to increase knowledge faster and get started with the dynamic plugin functionality.

Visualizing custom metrics is a common ask and therefore a potential good example to create such a template.

4. List any affected packages or components.
