Allow automatic scaling to be able to scale a service plan if the maximum number of the plan is reached
It would be very useful if when needed a website could upgrade the service plan from standard to premium in order to be able to have more than 10 instance running when scale out rules recommand that we need more.
It could also scale down when less than 11 instances is OK.
Sometimes we dont need bigger machines, but we need more instances !
Without that feature all that monitoring and plan scaling is done manually (with all the risks that this include)
