/*
Testcase Scenarios of hipGraphNodeFindInClone API:

Negative:

1) Pass nullptr to graph node
2) pass nullptr to original graph node
3) pass nullptr to clonedGraph
4) Pass original graph in place of the cloned graph
5) Pass invalid originalNode
6) Destroy the graph node in the original graph
   and try to get the deleted graph node
   from the cloned graph
7) Clone the graph,Add node to Original graph
   and try to find the original node in the cloned graph


Functional:

1) Get the graph node from the cloned graph corresponding to the original node
2) Create and clone the graph, modify the original graph and clone the graph again,
   then try to find the newly added graph node  from the cloned graph
