 ### -MaxPrice
-Specifies the maximum price you are willing to pay for a low priority VM/VMSS. This price is in US Dollars. This price will be compared with the current low priority price for the VM size. Also, the prices are compared at the time of create/update of low priority VM/VMSS and the operation will only succeed if the maxPrice is greater than the current low priority price. The maxPrice will also be used for evicting a low priority VM/VMSS if the current low priority price goes beyond the maxPrice after creation of VM/VMSS. Possible values are: any decimal value greater than zero. Example: 0.01538.  -1 indicates that the low priority VM/VMSS should not be evicted for price reasons. Also, the default max price is -1 if it is not provided by you.
