Blueprint for configuring a PNF
This is the first version of a blueprint, intended to be used to configure PNFs. The design considers that a blueprint will be created for each possible PNF. Change-Id: I4994149441257eb417b6d5f611e12cd81595177f Issue-ID: CCSDK-1107 Signed-off-by: ottero <rodrigo.ottero@est.tech>

-<!-- QUESTION
- lines 74-78 and 157-161: if I have to resolve the variables I need based on
- the pnf id, do I need to specify a restconf-connection? Another point, the
- connection is aimed to ODL, not to the PNF, so I am not sure what to fill
- for this model (lines 122-137)
