Provide an informative log of performed and pending operations

The "ipfs" command currently does not seem to have a way of observing what it is doing or what it is waiting for. This makes it difficult to diagnose sources of performance problems and errors in setup. It also seems to lead to lots of questions and submitted issues about "why is this slow" and "what is it doing".

The current "--debug" flag only outputs the config path for me, nothing more.

I'd suggest adding another flag that outputs information about what operations have been started, what operations have been completed, and what operations have timed out. A simple version of such a flag might just print a line for each event, though a screen oriented status display might be nice to have.
