// pollIndefinitelyAsNeeded is a terrible hack which is necessary because the Azure
// Storage API (and perhaps others) can have response times way beyond the default
// retry timeouts, with no apparent upper bound. This effectively causes the client
// to continue polling when it reaches the configured timeout. My investigations
// suggest that this is neccesary when deleting and recreating a storage account with
// the same name in a short (though undetermined) time period.
//
// It is possible that this will give Terraform the appearance of being slow in
// future: I have attempted to mitigate this by logging whenever this happens. We
// may want to revisit this with configurable timeouts in the future as clearly
// unbounded wait loops is not ideal. It does seem preferable to the current situation
// where our polling loop will time out _with an operation in progress_, but no ID
// for the resource - so the state will not know about it, and conflicts will occur
// on the next run.
