Extend the Troubleshooting document with how and what logs should be collected

[brianehlert]

When a customer needs support, there is a set of logs or configurations that are necessary to aid the person providing support.
The troubleshooting document should include a list of useful data points to collect and outline how to collect those.

Such as:

• situation x - this is how you deeply inspect a resource to see its events and full status
• situation y - this is how to retrieve NGINX logs, controller logs, etc.
• situation z - this is how to retrieve logs from a pod that had been killed.
