Review Comment:
   if feature is turned on and the action has no containers yet, give it a 
capacity of 1 on first decision iteration if total containers in use for the 
namespace are less than the limit * over provision ratio value, thereafter do 
the normal capacity calculation. 
   
   If this is still over the limit, give 0 capacity and follow the normal code 
path to turn on namespace throttling
