This patch adds the logic to initialize our DEFAULT_EXECUTOR based on the concurrency mode. If the OS_NOVA_DISABLE_EVENTLET_PATCHING env variable is set to "true" then we use ThreadPoolExecutor so the service will use native threads. Otherwise the service will keep using the GreenThreadPoolExecutor and therefore using Eventlet. There is a new config option `[DEFAULT]default_thread_pool_size` added to define the size of the ThreadPoolExecutor and the existing `[DEFAULT]default_green_pool_size` is deprecated. The two config options are independent and each of them is only used if the service is started with the matching concurrency mode. Our test fixture that catches leaked threads are adapted to handle both threading mode. But at the moment it is only tested with the eventlet mode as no service can be switched to threading mode yet.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
