This convenience was necessary to be used for golang library functions like io.Copy and io.Pipe where we shouldn't be writing proxies and alternatives returning *probe.Error This change also brings more changes across code base for clear separation regarding where an error interface should be passed encapsulating *probe.Error and where it should be used as is.
