Description

The delete function as implemented by AzureNativeFileSystem store attempts delete without a lease. In most cases this works but in the case of a dangling lease resulting out of say a process killed and leaving a lease dangling for a small period a delete attempted during this period simply crashes. This fix addresses the situation by re-attempting the delete after a lease acqusition in this case
