post http://127.0.0.1:8080/subnets/configured
This api is used only for the older appliance whose version is less than 8.1.7.0.
The subnets list in the request body will be compared to the list of current subnets configured on the appliance. Any subnets which are in posted list but not on the appliance are added. Similarly, missing subnets are removed. Matching subnets are updated.
