It seems that ListConfigurations() calls return all configurations, including those whose storage lease has expired. We would like to be able to exclude these configurations from the results, but can see no way to distinguish between an expired configuration and an unexpired configuration. we are currently using the v3 api. Looking at v4 it seems there are additional methods and members relating to leases, but still nothing that would enable us to figure out if a configuration's storage lease had expired.

Is there any way to achieve this? Or at least is there a way to determine if a config has expired from any other properties?
