Update debug-operator.md

Hi @coro 
Thanks for including me in this review. I made direct updates above. Some additional questions please (note, a lot of these questions is around profiling and my lack of knowledge on it: "Profiling is the act of analyzing the performance of applications in order to improve poorly performing sections of code. One of the most popular ways to visualize a profile and quickly identifying performance issues is by generating a Flame Graph" I guess if you think customers will know about profiling then the text in the steps below is clear) 

1. "Patch the Operator Pod that you want to profile with the `ENABLE_DEBUG_PPROF` environment variable set to `True`. What does "Patch the Operator Pod that you want to profile with..." mean, does it mean you have to enable this pprof tool on the operator that you want to extract debug information from, if so how about rewording like this: "Enable the `ENABLE_DEBUG_PPROF` variable on the operator that you want to retrieve debugging information from by running the following command. Note, this example is for the cluster operator:

2. I don't know what a `port-forward` operation is, "complete a `port-forward` operation to the Operator Pod using kubectl" will our customers know what this means if so, it is ok? If not perhaps we need further clarification here.

3. "Forward to the metrics port on the Operator Pod"??? forward what to the metrics port? Again this could be my lack of understanding @coro if you think customers will know then it is fine.

4. The new step 3 "In a separate terminal, you can now use the <code>go tool pprof</code> to profile the Operator Pod." what does profile the Operator Pod mean? again same applies, if you think a customer will know that it is fine, if you think they won't then we need to simplify it. 

5. In the table, I changed references to "A sampling" to "A Sample" , does "A sample" in this context mean "some of them", will it leave the customer wondering well what about the rest of them? Do I need to see them all, what if what I want is not in this sample?
