fix: nodename quotation issue

* update nodename method to not use regex anymore
* update readme with 2 new columns for the exit code table

We used quite the broad regex to parse the nodename from the status
string. But we relied on a single quote to mark the starting point.
It seems some distributions don't have this starting quote,
therefore breaking the api.
