Reverts removal of from_json on ServerProfile cls
Reverts removal of from_json on ServerProfile cls

The method was doing something different from the one on OneViewObject: It was
adding keys on the ServerProfile object that weren't on the attribute_map.
Without it, Bad Requests are being sent to OneView since they doesn't had the
required parameters.

Reverting it back and fixing the problem of the instatiation on the old method.
