Function instantiation feature

Functions are instantiated as a consequence of the instantiation of the service they are part of (see Service instantiation), i.e., there is no way to request the instantiation of a function from the outside of the MANO Framework and it's Function Lifecycle Management component.

Function records

After having been successfully instantiated, a record is saved in a repository. Those records can be accessed, for instance, to know which IP address it has.

Private functions

add licence verification
