SCPFscalingMaxIntens Tests
    - Use retry function to set up Apps
    - Update the sleep time, make sure this is enough
    - Fix a bug, reset CLIs list every time
    - Using REST API to activate apps and verify intents and flows

+Summary:
+        This is a performance test suit, designed to test the upper limits
+        of onos and ovsdb with respect to installing intents.
+        In this test, CASE10 set up null provoder, CASE 11 set up ovs. Start from
+        1 node, and scale to 7 nodes.
+        We push intents to every node by using Thread, and when the intents number
+        reach to the minimun number, we will verify intents and flows. If intents are
+        not installed correctly, test will stop pushing and finish this case.
+NOTE:
+        This test is largely based on the hardware used to run onos and mininet.
+        Therefore, results will very test station to test station.
