doc: remove confusing docs about aggregate allocation ratios
Change Ifaf596a8572637f843f47daf5adce394b0365676 added a note about the behavior change in Ocata where allocation ratios set on host aggregates was ignored because of placement resource provider allocation ratios being used. Later, change I7d8e822cd40dccaf5244e2cd95fa1af43fa9ed87 added a lot more detail about allocation ratios in the scheduler docs including the initial* allocation ratio config options. The note from the previous change was moved and as a result leads to some confusion since the doc starts by saying essentially, "you can use these aggregate filters to manage allocation ratios on a set of hosts" and then the immediate note says essentially, "oh btw that doesn't work since ocata, sorry!". To avoid the confusion, this simply removes the part about how the aggregate filters can be used to manage allocation ratios.
