HPA discovery&registration

	workflows:
	    Step 1: Prepare a Cloud Region(Titanium Cloud instance) for on boarding
		1), generic capacity dimension: vCPU, RAM, Storage,etc.
		    medium, large
		2), HPA dimension: CPU Pinning, CPU topology, NUMA, HugePage, etc.
		    HPA set1: None HPA involved
		    HPA set2: CPU policy=dedicated, NUMA=2, HugePage size=2048KB
		    HPA set3: CPU Policy=shared, HugePage size=2048KB
		3), setup below flavors by combining HPA dimension and generic capacity dimension
		    onap.hpa.set1.medium 
		    onap.hpa.set1.large
	        onap.hpa.set2.medium
		    onap.hpa.set2.large
		    onap.hpa.set3.medium
            onap.hpa.set3.large
					
	    step 2: On board a Cloud Region (Titanium Cloud instacne) via ESR portal
		http://{ESR portal endpoint}/iui/aai-esr-gui/extsys/vim/vimView.html
	        For example:
                http://10.12.7.8/iui/aai-esr-gui/extsys/vim/vimView.html			
		
	    step3: Verify Cloud Region (Titanium Cloud instacne) representation via Postman
		checkpoints:
    		1), cloud region object
                complex-name
		        relationship to that complex object
	        2), tenants
	        3), flavors, HPA capabilities
