When transforming a NodeConf struct to a NodeInfo (get the NodeInfo from
the Nodconf) nested structures were seperately handled. This means there
were seperate handles for e.g *Netdevs and *IpmiConfig. The new getter
traverses through the datastucture and sets the right value for an Entry
struct, but calls itself again if a Pointer is detected.
This adds the posiblity to add new nested structures to NodeConf and
NodeInfo without the need of seperate handling them in the transformer
functions.
