Currently on failure we don't attach stderr and stdout of a command (we do stderr sometimes but its not consistant. This pr achieves that by passing in stdout and stderr to the error.
It also solves the problem of potentially storing to much data in memory (lets say stdout of a long running task) by capturing stdout and stderr in ring buffers, and storing only the last 32 lines to be printed.
This pr is to follow up on this pr: #234 by @stanislavkozlovski
