+Find Max Switches By Scaling
+ [Documentation] Find the max number of switches from ${start} until reaching ${end} in steps of ${increments}. The following checks are made through REST APIs:
+ ... -\ Verify device count is correct
+ ... -\ Verify device status is available
+ ... -\ Verify device roles are MASTER (default role in case of standalone controller)
+ ... -\ Verify topology recognizes corret number of devices (Through api "/topology")
+ ... -\ Observe each device individually
+ ... -\ Observe links, hosts, and flows through the controller
+ ... -\ Observe device info at lower level on mininet (Written for PoC). Shows flows, links, and ports. Checks can be easily implemented at that level as well
+ ... -\ STOP Mininet Topo
+ ... -\ Verify device count is zero
+ ... -\ Verify topology sees no devices (Through api "/topology")
