Support all Metadata Annotations for Json Schema Milestone

[jl-beast]

Currently from what I see in the Milestone, the implementation of the following basic metadata annotations from the json-schema.org have not been mentioned:

• "deprecated"
  • could be implemented by showing a [deprecated] annotation to the far-right side of the renderer.
• "examples"
  • could be implemented for values by allowing for a drop-down underneath if examples are provided. When an Example is selected it would load it in. Would only be needed for string, number, and integer values.

the "readOnly" and "writeOnly" annotations would need to be specific to kubeApps, so I am not sure what purposes they would be used for.

I'm having a look at it now. For instance, using readOnly for disabling fields:

Edit: and using the examples:
