/**
Test Case Scenarios of hipGraphHostNodeGetParams API:

Functional Scenarios:
1) Create a graph, add Host node to graph with desired  node params. Verify api fetches the node
params which were mentioned while adding the host node. 2) Set host node params with
hipGraphHostNodeSetParams, now get the params and verify both are same. 3) Create graph, Add Graph
nodes and clones the graph. Add Host node to the cloned graph, update hostNode params using
hipGraphHostNodeSetParams API  now get the params and verify both are same

Negative Scenarios:

1) Pass pGraphNode as nullptr and verify api doesn’t crash, returns error code.
2) Pass pNodeParams as nullptr and verify api doesn’t crash, returns error code.
3) Pass uninitialized graph node
