Requirement of cmd run successfully in all operations.

This seems like an overkill. Even though the improvement received might be in small units, it is but a logical step to not log for successful run of a command. The reasoning being just stating running command xyz on node or nodes xyz without showing any errors for the same command, will imply that it succeeded, hence we can eliminate these success logs.

I disagree with the statement "just stating running command xyz on node or nodes xyz without showing any errors for the same command, will imply that it succeeded" - There are numerous cases in which an error can occur without actually being propagated back (simplest example is deadlock on the server which will cause prevent the command result from even returning), in these case, without specifically logging a success/failure, it'd be impossible to determine success with 100% certainty.

We have a timeout option in remote executioner code which prevents such operations from happening. So deadlock preventing the framework from moving ahead is not in question.
