Fix log_console_output call in test_network_basicops
Fix log_console_output call in test_network_basicops

The call is currently iterating over self.servers expecting it to
return a key-value pair. That would be true for self.server.items or
self.server.iteritimes, but not self.server.

This patch just passes self.servers.keys to log_console_output
