Further expansion of the warning regarding self-parting

Your feedback

X would like to see us further describe how to treat a self part, the process of self parting and status checking from a separate node, and how to treat the return codes.

They suggest that the documentation should include documentation of how to properly part a node from itself e.g. how to interpret error codes, how to check for completion, etc.

The documentation should include more description of the concerns and how to deal with them.
