   @markap14 @ijokarumawak Everything in this PR appears to work in terms of 
saving to registry and importing, but I did want to ask what should happen when 
there are public ports with the same name in multiple process groups?
   
   For example, I setup PG1 with public Input Port "IN" -> Update Attribute, 
and save it to registry. Then I created a GenerateFlowFile -> RPG connected to 
the "IN". Then I import a new PG and choose the same one I just saved to 
registry, so now I have two of the same PGs, both with an input port named "IN".
   
   It seemed as though the RPG never recognized the second and continued 
sending to the original one. Then I renamed the second input port to "IN2" 
which showed as a local change on the PG, and I stopped the original input 
port. The RPG somehow refreshed and renamed the connection from "IN" to "IN2".
