! Backwards compatibility warning
The output of get_embedded_health changed: the network interfaces are now
returned as a list instead of a dict that's keyd on the port name, as port
names are not unique. This will make iLO interfaces and interfaces on
non-primary nic's show up in the output.
* call_delayed now handles exceptions (such as those caused by calling
unsupported functions) better
* Support for more new methods and attributes
