Log API Call errors

[dann1]

It can be possible that API Calls issued to OpenNebula, like one.image.allocate or one.template.allocate fail. When they do so, there is no error message, just a failure notification. To see what the problem is, we have to look into oned.log, which means going out of the scope of one-swap.

For example
