"fetch failed" logged without retry information

[arty-name]

When running npm install in normal mode without -d it sometimes reports fetch errors but finishes successfully. Install is successful because npm attempts fetching several times. However it's not clear from the logs.

I propose reporting fetch errors only when all the attempts fail. Another option is to log "fetch failed, will retry".

Another option is to log "fetch failed, will retry".

This is what I think makes the most sense. If somebody wanted to put together a patch with this tweak to the error message (it probably belongs in npm-registry-client), it would be welcomed.

The default message is fine, but it doesn't get displayed by default anymore, because the default logging level is warn, and those messages were being logged at info, which is lower priority. Since these really are warnings, go ahead and log them as such. Landed as 9bb2c34.

Thanks, that option also works for me :)
