WL-3181 Set a default timeout on import HTTP requests.

60 seconds on connection, 30 seconds on socket.
Log which job failed when something goes wrong.

When an import fails we should log the configuration that was being used so it's easier to debug which import is failing. We are careful to not write the password out into the logs.
WL-3181 Make it clear they are just the defaults.
