[Docs]: Flow chart for callbacks

[ringerc]

Is there an existing issue already for your request/idea?

• I have searched for an existing issue, and could not find anything. I believe this is a new documentation enhancement to be evaluated.

What problem in the existing documentation this issue aims to solve?

While writing a CNPG-I plugin, I found it to be unclear under what circumstances each callback would be invoked, and what each callback could do.

Describe what additions need to be done to the documentation

A flow chart would be very helpful for this. It would show things like:

• Order of calls
• Which callbacks are made at plugin or CNPG startup
• possible outcomes of calls

For example, show that on plugin start the plugin reconciler hooks are called for each Cluster resource, but the operator lifecycle hooks won't be.
