Events documentation is out of date and misleading

[berndtj]

Bug Report

All of the "Guides" associated with events are out of date and misleading. They continue to refer to build in event driver types which are no longer built in and they do not point to the location of the source of truth which is found in one of the dispatchframework repositories.

We should include a table listing out all known eventdriver and links to repositories which include documentation and usage.

Expected behavior

Documentation is accurate

Current behavior

Documentation is misleading

Steps to reproduce

Impact

• [ ] Low - Annoyance, but does not impact business or functionality
• [ ] Medium - Issue can be worked around, but is causing pain
• [x] High - Blocker

Possible solution

Your Environment

• Dispatch CLI version (or git commit):
• Dispatch Chart version (or image[s] tag):
• Operating System and version:
• Kubernetes version (and distribution):
• Etc (any other useful environmental information):
