/**
Testcase Scenarios :
Negative -
1) Pass node as nullptr and verify api returns error code.
2) Pass un-initialize node and verify api returns error code.
3) Pass pNodeParams as nullptr and verify api returns error code.
Functional -
1) Add Memcpy node to graph, update the Memcpy node params with set and
   launch the graph and check updated params are taking effect.
2) Add Memcpy node to graph, launch graph, then update the Memcpy node params
   with set and launch the graph and check updated params are taking effect.
