* Fix performance issue on server when server fails to load image file.  Currently server retries an API call 3 times before it fails, at which point it'll sleep the thread for 2 secs.  This becomes problematic when there are alot of SDK errors.  I'll create seperate issue to refine the retry logic to not be so expensive on the server.

VDL is set to retry an pybinded API call multiple times in case the call fails the first time.  The issue is the method lib.retry will sleep the thread for 2 seconds after an exception.  Since VDL was not running in threaded mode, this causes all request to the server to stop immediately, therefore even requests to get static resource are frozen.  This change enables threaded mode in flask. (#249)
