Allow querying tag in listKeyValues

In situations where startup times are imperitive then it would be good to be able pre filter the list of returned values based upon tag. We can use listKeyValues api call to get the key and and value in one api call (only having to do key vault queries afterwards) but for a large key store paging would come into play. As an example I would like to tag keys with "RabbitMq" and "MainSqlDatabase" then I can fetch only the relevant keys

listKeyValues?tags=RabbitMq,MainSqlDatabase

Or perhaps settings relevant to the application

listKeyValues?tags=ApplicationX
